Frequently Asked Questions About RWMA / Resistance Welding Alloys
Answers drawn from the ALB technical data for this page.
Which alloys does ALB recommend for the rwma industry?
Beryllium copper, high conductivity copper, resistance welding alloys and the bronze families listed on this page are all supplied into this industry. Each grade data sheet gives the composition, physical properties and specification.
Can ALB supply finished components as well as material?
Yes. Beryllium copper rings, sleeves, plunger tips, EMI finger stock, welding electrodes, drill string components and canted coil springs are produced to customer drawing.
Which standards are the alloys produced to?
Production and certification are in line with national and international standards such as ASTM, DIN, RWMA and AMS, and all ALB subsidiaries are certified to ISO 9001:2000 Quality Management System.
