beryllium copper C17200
 Cube2--C17200 (CDA 172) Beryllium Copper is the most commonly utilized Copper Beryllium alloy and is notable for its highest strength and hardness compared to commercial copper alloys. C17200 alloy contains appr. 2% of beryllium and achieves its ultimate tensile strength can exceed 200 ksi, while the hardness approaches Rockwell C45. Meanwhile, the electrical conductivity is a minimum of 22% IACS in the fully aged condition.C17200 also exhibits exceptional resistance to stress relaxation at elevated temperatures.

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.
 
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,worm gear etc.
