What is the difference between 1060 and 3003 aluminum?

Characteristics and application scope of 1060 aluminum alloy

1060 is formed by adding a small amount of copper element to pure aluminum, which has excellent forming processing characteristics, high corrosion resistance, good weldability and electrical conductivity. 1060 is widely used in products that do not require high strength, such as chemical instruments, sheet metal processing parts, deep-drawn or spinning concave utensils, welded parts, heat exchangers, clock surfaces and disk surfaces, nameplates, kitchenware, decorations, reflective appliances Wait.

Mechanical properties of 1060 aluminum:

Tensile strength σb (MPa) ≥75

Conditional yield strength σ0.2 (MPa)≥35

Specimen Size: All Wall Thicknesses

Note: Longitudinal mechanical properties of pipes at room temperature

Heat treatment range of 1060 aluminum:

Rapid annealing: the heating temperature is 350-410℃; the holding time is between 30-120min depending on the effective thickness of the material; air or water cooling. High temperature annealing: heating temperature is 350 ~ 500 ℃; when the thickness of the finished product is ≥ 6mm, the holding time is 10 ~ 30min, <6mm, until the heat penetrates; air cooling. Low temperature annealing: heating temperature 150 ~ 250 ℃; holding time 2 ~ 3h; air or water cooling.

The characteristics and application scope of 3003 aluminum alloy:

3003 is an AL-Mn alloy, which is the most widely used anti-rust aluminum. The strength of this alloy is not high (slightly higher than that of industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are used to improve its mechanical properties: It has high plasticity in the annealed state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. Mainly used for low-load parts that require high plasticity and good weldability, and work in liquid or gas media, such as mailboxes, gasoline or lubricating oil conduits, various liquid containers and other small-load parts made by deep drawing: The wire used to make the rivet 3003 aluminum plate has good formability, weldability and corrosion resistance. It is used for processing parts and components that require good formability, high corrosion resistance and good weldability, or work that requires both these properties and higher strength than 1XXX series alloys, such as kitchenware, food and chemical products handling and Storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes processed with thin plates, general utensils, heat sinks, cosmetic plates, photocopier rollers, and ship materials.

The chemical composition of 3003 aluminum alloy:

Silicon Si: 0.60 Iron Fe: 0.70 Copper Cu: 0.05-0.20 Manganese Mn: 1.0-1.5 Zinc Zn: 0..10 Others: Individual 0.05, total 0.15 Aluminum Al: Balance

Mechanical properties of 3003 aluminum

Note: Longitudinal mechanical properties of pipes at room temperature

Hot working and heat treatment temperature of 3003 aluminum

The homogenization annealing temperature is 590~620℃, the hot rolling temperature is 480~520℃, the extrusion temperature is 320~480℃, the typical annealing temperature is 413℃, and air cooling.

Aluminium alloys Description of the basic state

“F” Free machining state is applicable to products without special requirements for work hardening and heat treatment conditions during the molding process, and the mechanical properties of the products in this state are not specified.

The “O” annealed condition applies to processed products that have been fully annealed to obtain the lowest strength.

“H” Work Hardened Condition Applies to products that have been increased in strength by work hardening, which may or may not have undergone additional heat treatment to reduce strength after work hardening.

“W” Solution heat treatment state Treatment state An unstable state, only applicable to alloys that are naturally aged at room temperature after solution heat treatment, and this state code only indicates that the product is in the natural aging stage.
