Beryllium copper C17200
Beryllium copper is based on beryllium as the main alloy of copper
alloy, also known as beryllium bronze. It is the best performance
of copper alloy in the high-performance elastic material, a high
strength, flexibility, hardness, fatigue strength, elastic lag
small, corrosion resistance, wear resistance, cold, high
conductivity, non-magnetic, impact does not produce sparks A series
of excellent physical, chemical and mechanical properties.
Beryllium copper tape used in micro-motor brush, cell phone,
battery.

Applications
Beryllium Copper is widely used in mold core, injection mold
insert, mold cavity, corrosion resistant die, die casting
machine head, watering the crossing thimble, the punch mould parts,
hot runner system such as accessories,
stretching die, casting mould, die-casting mould, and corrosion
resistant wear resistant parts such as bearings,
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.
