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,
FAQS:
