Group A: copper base material
RWMA |
HOSO code |
Application and Description |
Class 2
|
HOSOCU®202 Chromium Zirconium copper |
Better Hardness than HOSOCU®201 but lower electrical conductivity, common used for the spot and seam welding of cold and hot-rolled steel, stainless steel and low conductivity brass and bronze. They are also used as flash welding dies and as electrodes for the welding of galvanized steel and other coated materials. |
HOSOCU®203 Chromium copper |
Same application as HOSOCU®202, less loading capability. |
|
Class 3 |
HOSOCU®302 Cobalt-beryllium copper |
Very high hardness use for the high loading spot and seam welding. Such as stainless steel, chrome and monel metal. |
HOSOCU®303 Beryllium-free copper |
||
Class 4 |
HOSOCU®400 Beryllium copper |
For extremely high loading application. |
Group B: No-ferrous metal
