RWMA Class 4 Beryllium Copper Alloys With 1.8% Be/Cu Alloy 25 Strip
Mateial Introduction of RWMA Class 4 Beryllium Copper Alloys/Alloy 25:
RWMA Class 4, BERYLLIUM-COPPER has extremely high hardness, and is recommended for projection, flash and butt-welding dies. It has lower conductivity than Class 3 alloy but it is harder and more wear resistant. It should be considered where there is concern with high-pressure density and severe wear, but where heating, due to its low conductivity, is no excessive.
It is used frequently in the form of inserts, die facings, and seam welder bushings. It is available in the annealed condition, which is more readily machined, and then subsequently heat-treated.
It is also Known as CuBe2, UNS. C17200.
