BERYLLIUM COPPER ALLOY
172 (UNS C17200) per
ASTM B 194
Properties of BERYLLIUM COPPER:
Chemical composition: Cu 98.1%, Be 1.9%
Temper as stamped: TD01
Properties after heat treatment (TH01):
Hardness: 36-43 Rockwell C
Mechanical Life: 100 Cycles Min.
Density: .298 lbs/in3
Electrical Conductivity: 22% IACS*
Resistance: 10 miliohms Max
Operating Temperature: -55°C/+125°C
Melting point: 980°C/865°C (liquidus/solidus)
Stress Relaxation†: 96% of stress remains after
1,000 hours @ 100 °C ; 70% of stress remains after
1,000 hours @ 200 °C
*International Annealed Copper Standard, i.e. as a % of pure copper.
†Since BeCu loses its spring properties over time at high temperatures; it is rated for continuous use up to 150°C. For
applications up to 300°C, Mill-Max offers many contacts in Beryllium Nickel. Contact Tech Support for more info.

Compliance Statement for DRC Conflict Free products.
Reference:
Dodd-Frank Wall Street Reform and Consumer Protection Act, Section 1502, reporting requirements for users of conflict
minerals.
“Conflict minerals,” are Columbite-tantalite (coltan), cassiterite, gold, wolframite, or their derivatives; or any other mineral or
its derivatives determined by the Secretary of State to be financing conflict in the Democratic Republic of the Congo (DRC) or
an adjoining country. Metals derived from these minerals are tin, tantalum, tungsten, and gold. By this definition, the only
minerals of concern that may be found in Mill-Max products are tin and gold.
Mill-Max Mfg.Corp. hereby certifies that its products are manufactured with tin and gold that is derived from material that is
considered DRC Conflict Free. Mill-Max provides this assurance as a result of a due diligence process that includes traceability
to the source and in some cases the identification of recycled and scrap materials included in the subject material.
