Product Introduction

3105 aluminum coil is essentially a pure high-quality aluminum alloy containing 98% aluminum. With trace amounts of alloying elements added, it has higher strength than 1100 and 3003. It has good deep drawing performance and processing performance. It has high plasticity under quenching. In semi-cold hardening, the plasticity is still stronger, low plasticity, excellent corrosion resistance, excellent electric welding weldability and cold hardening. The drilling performance under chemical conditions is poor.

Product Advantages

1. Good electrical conductivity. Due to the addition of 0.3% copper, the conductivity of 3105 aluminum can reach 41%.
2. 3105 aluminum coil strip has good rust resistance and corrosion resistance.
3. 3105 aluminum alloy has good processing properties and excellent weldability, so 3105 aluminum coils are used in bottle cap design, with novel shapes and long-term use.
4. 3105 aluminum coil has high plasticity and is in a progressive state.
