C1720 Beryllium copper alloy strips 0.8mm thick 200mm width
Copper-beryllium 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.
Beryllium Copper is a copper alloy with the optimum combination of
mechanical and physical properties such as tensile strength,
fatigue strength, performance under elevated temperatures,
electrical conductivity, bending formability and corrosion
resistance. Beryllium Copper is widely used as contact springs in
various applications like connectors, switches, relays, etc.

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.
