3105 aluminum coil is a non-alloyed, heat-treatable aluminum alloy used in many applications over the years. It’s best known for its corrosion resistance, making it ideal for marine applications.

Properties of 3105 Aluminum Alloy

The 3105 aluminum alloy is composed of 90% aluminum, 4% copper, 4% manganese, and 1.5% silicon. With a tensile strength of about 172 MPa, this material is flexible enough to be formed into many shapes without cracking and strong enough to withstand corrosion.

3105 aluminum coil is a high-quality, lightweight aluminum alloy with a hardness of 45 HB. It has excellent weldability and can be used in many applications.

The properties of the 3105 aluminum coil are as follows:

1) The product is non-magnetic and has a high electrical resistance. It conducts heat well and dissipates it quickly.

2) Its tensile strength is high, but its elongation rate is relatively low. This means that it will not deform easily when bent or stressed.

3) It has a high yield strength and good ductility.

3105 Aluminum Coil versus 3003 Aluminum Coil

3105 aluminum coil is an excellent choice for many applications. It has a higher strength than the 3003 aluminum coil, meaning that it can be used in applications that require more rigidity or resistance to impact damage. 

It also has a lower density than the 3003 aluminum coil, meaning it is lighter and easier to transport. Finally, the 3105 aluminum coil has a lower thermal conductivity than the 3003 aluminum coil, making it better suited to applications where heat transfer is an issue (such as in electronic equipment).

It is commonly used to construct aircraft structures like fuselages and wings, yacht and small utility boats, flashlights, scuba tanks, high-pressure gas storage cylinders, aluminum cans, and automotive parts. 

What does the 6061 mean in the aluminum coil?

6061 is the designated grade for precipitation-hardened aluminum alloy. It was developed in 1935 and was originally known as “Alloy 61S”. Its chemical composition is 95.85% aluminum, 0.80% Manganese, 0.40% Silicon, 0.15% Copper, and 0.04% Chromium. 

Its mechanical properties vary depending on the heat treatment or temper of the material. The combination of silicon and magnesium allows the 6061 aluminum coil to withstand heat treatment and attain a higher strength level. 

Properties of 6061 Alloy Aluminum Coil

• Lightweight: Aluminum is a light metal perfect for cabling and wiring applications. It eliminates the use of supporting structures, making it a cost-effective solution. Using a 6061 aluminum coil increases payload and improves the fuel economy of both transportation and automotive industries.
• Resistant to corrosion: This material offers high resistance against corrosion due to harsh environmental elements such as moisture, oxygen, and chemicals.
• Versatile and formable:  It is ideal for thinner applications like making kitchen coil and for more durable applications, including creating aircraft or military armor. And while it has 13 KSI tensile strength, it can be strengthened up to 100 KSI by adding alloying elements or subjecting it to cold working methods. This makes the 6061 aluminum coil a good material for structural applications. 

6061-O vs. 6061-t6 

6061-O (annealed) is a pre-tempered grade aluminum coil with a 150 MPa or 22 KSI maximum tensile strength. It yields 83 MPa (12 KSI) to 110 MPa (16 KSI).  This aluminum material has 10-18% elongation or stretch. The alloy is usually heated for 2-3 hours at 415 °C to achieve the desired annealed condition.

6061-T6 grade aluminum coil is artificially aged and solutionized to deliver the maximum yield strength. With a minimum yield strength of 240 MPa (35 KSI) and ultimate tensile strength of 290 MPa (42 KSI), it has a good-strength-to-weight ratio. 

T6 refers to the degree or temper of hardness attained through precipitation hardening. It is one of the common materials that is used for structural and engineering applications. It offers excellent weldability and formability.

What does 3003 mean in aluminum coil?

The numbers in the aluminum coil are the alloy code, which tells you what elements are in the alloy. The first number refers to its most significant alloying element. The second number indicates the alloy’s variation (if different from zero), and the third and fourth number identifies its series.

For the 3003 aluminum coil, the first digit ‘3’ means it is an alloy in the manganese series, the ‘0’ means it has no variation, and the last numbers ‘03’ means it is from the 3000 series. This numbering scheme is based on the International Alloy Designation System.

Properties of 3003 alloy aluminum coil

3003 aluminum coil has a chemical composition limit of 0.6 silicon, 0.7 iron, 0.05-0.20 copper, 1-1.5 manganese, 0.10 zinc, and 0.15 from other elements.

3003 aluminum has a tensile strength of up to 200MPa, and all methods can readily weld it. It is resistant to corrosion in most environments except when exposed to seawater or other corrosive atmospheres containing chlorine or fluorine.

3003 alloy aluminum coils come in various shapes and sizes—ranging from sheets just 0.4 mm thick to 12 mm thick tubes. There are plenty of options when deciding on materials for each project. They’re also available in coils (for industrial use) and straight lengths (for commercial projects).

3003 Aluminum Coil vs. 3004 Aluminum Coil

3003 aluminum coil and 3004 aluminum coil are both used in a wide range of applications. While they are similar, they are not identical, and each has its benefits and drawbacks.

The 3003 and 3004 alloys are similar in composition, but 3004 has an additional 1% magnesium, making it slightly stronger. This results in better corrosion resistance when exposed to acid environments, making this alloy more expensive to produce than the 3003 alloys.

The 3003 aluminum alloy offers better ductility than the 3004 alloy and weldability due to its lower magnesium content; however, it has a lower strength-to-weight ratio than the latter material because of its lower density.

Concerning environmental application, 3003 can be heat treated and cold worked, but 3004 can only be cold worked.

5052 aluminum alloy coil contains 2.5 percent magnesium and 0.25 percent chromium. Its lightweight and corrosion-resistant properties make it suitable for the marine environment, aircraft fuel tanks, architecture, manufacturing, and more.

What does 5052 mean in aluminum coil?

Each alloy grade has a four-digit number, such as 5052. The first number represents the grade’s main alloying element or the series it belongs. 

The second number is usually a zero. If not, it represents the alloy variation. The third and last numbers represent the specific alloys in the series. Today’s major alloying elements include silicon, iron, copper, manganese, and magnesium. 

5052 aluminum coil belongs to the 5000 grade. It starts with the number 5 because its central alloying element is Magnesium. Sometimes, they also alloy manganese with magnesium in the 5000 series.

The last two digits, 52, represent the grade in the 5000-grade category. These digits differentiate them from the other alloy grades, such as 5059, 5083, 5086, and more. 

Hence, 5052 in aluminum coil means that the aluminum coil is alloyed with magnesium and belongs to the 5000 series.  

Properties of 5052 alloy aluminum coil

5052 aluminum coil is a popular alloy grade because of its versatility. The alloyed magnesium gives good aluminum weldability, higher fatigue strength, and corrosion resistance.

It also has commendable fatigue strength with a limit of 115 MPa in the H32 tempers and 123 MPa in the H34 tempers. With superb versatility, it has become one of the most widely utilized non-heat-treatable aluminum alloys in everyday use.

What is the difference between 5052 H32 and 5052 H34?

5052 H32 and 5052 H34 have the same alloy composition. Hence, they are variants of the same material.  They are the most widely used 5052 aluminum plate. However, they have different mechanical properties.

The H3 portion denotes the incomplete annealing and hardening of the aluminum sheet. The aluminum sheet needs stabilization to avoid it becoming too soft. The next digit then indicates the hardness grade. As the number increases, so do the hardness level and grade.

5052-H32 Aluminum is a quarter-hard temper, while 5052-H34 Aluminum is a half-hard temper. Another hardness grade is “6”, which stands for 3/4 hardness, and “8”, which stands for full hardness.

After baking at high temperature to form a film, the molecular structure in the coating is tight, and it has super weather resistance. Fluorocarbon coatings can be divided into traditional fluorocarbon and nano-fluorocarbon coatings according to the surface film-forming structure. Especially suitable for decoration and display of indoor and outdoor decoration, commercial chains, exhibition advertisements in public places.
