3105 aluminum alloy has good corrosion resistance, good plasticity and processability, and the performance of gas welding and arc welding is good. 3105 aluminum has slightly higher strength than 3003 aluminum, others properties are similar to 3003 aluminum alloy. 3105 aluminium has good anti-rust property, good conductivity, electrical conductivity can be up to 41%, 3105 aluminum sheet has high plasticity in the annealing state, in the semi cold hardened, the plasticity is still better, it has low plasticity, good corrosion resistance, good weld-ability and poor cutting properties in cold hardening state.

What is the difference between 3003 and 3105 aluminum alloy?


3105 aluminum alloy has good corrosion resistance, good plasticity and processability, and the performance of gas welding and arc welding is good. 3105 aluminum has slightly higher strength than 3003 aluminum, others properties are similar to 3003 aluminum alloy.

What is aluminium alloy 3105 used for?

Aluminum alloy 3105 is essentially a 98% aluminum alloy with minor additions to increase strength over that of alloy 1100 and 3003. It is not hardenable by heat treatment and it has good corrosion resistance, formability and weldability. Aluminum alloy 3105 is most commonly used where a painted finish is desired.

The chemical composition of 3105 aluminum are:
Aluminum Al: allowance
Silicon- Si: less than 0.6%
Copper-Cu: less than 0.30%
Magnesium-Mg:0.20 ~ 0.8%
Zinc-Zn: less than 0.40%
Manganese-Mn:0.30 ~ 0.8%
Titanium-Ti: less than 0.10%
Chromium-Cr: less than 0.20%
Iron-Fe:0.000 ~ 0.700%

     4. Packaging 

    In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging：

According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.

Packing standard: according to the following national standard requirements (the parts beyond the requirements will be specified separately)

GB／T191 packaging-pictorial marking for handling of goods

GB／T4857 (all parts) basic test for transport packages

GB／T4879 rustproof packaging
