Product Details

Xhm (TM06) / Xhms (TM08) Harden Copper Alloy Strip beryllium Coper Tape C17200 Qbe2 Strip

Shanghai Tankii Alloy Material Co.,Ltd is the leader company in the manufacture of beryllium-copper alloys. We actively participate in all environmental studies made on all substances used in our products. Our priority is to comply with all legal regulations in force to ensure the continued existence of our products to our clients.

Beryllium-Copper-alloys are mainly based on copper with a beryllium addition. High strength beryllium copper alloys contain 0.4-2% of beryllium with about 0.3 to 2.7% of other alloying elements such as nickel, cobalt, iron or Lead. The high mechanical strength is achieved by precipitation hardening or age hardening.
It is the best high-elastic material in copper alloy. It has high strength, elasticity, hardness, fatigue strength, low elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, no magnetism, no impact, no sparks, etc. A range of excellent physical, chemical and mechanical properties.

Features
1. High thermal conductivity
2. High corrosion resistance, especially suitable for polyoxyethylene (PVC) products mold.
3. High hardness, wear resistance and toughness, as inserts used with mould steel and aluminium can make the mold play a highly efficient, prolong the service life.
4. Polishing performance is good, can achieve high mirror surface precision and complicated shape design.
5. Good tackiness resistance, easy to welding with other metal, easy to machining, there is no need additional heat treatment.
