Differentiation between CuCrZr & Beryllium copper
This information is usefull to those who work in Automotive Bodyshop. Kindly go through the table below for differentiation between CuCrZr & Beryllium copper . You can add your comments or questions.
| Comparison & Differentiation for CuCrZr & Nickel Silicon copper Alloy(SA100) | |||
| SrNo: | Description |
CuCrZr (C18150) RWMA II |
R100(Nickel Silicon Copper)/Beryllium copper RWMA III |
| 1 | Conductivity(IACS) | 80 - 85 % | 40 - 47 % |
| 2 | Hardness (Rb) | 83B | 90B |
| 3 | Heat Generation | Less due to high conductivity | Very high due to less conductivity |
| 4 | Crack Formation | No Chances | More chances due to high heat generation & material becomes brittle due to more hardness. |
| 5 | Recommendation by RWMA |
Recommended for high level production spot and seam welding of clean mild steel, low alloy steels, low conductivity brasses and bronze. |
Recommended for spot welding and seam welding steels having high electrical resistance, such as stainless Steels,Nichrome & Monel |
| 6 | Tensile Strength (PSI) | 75000 | 90000 |
| 7 | Power Consumption | Comparatively less | Comparitively High |
| 8 | Parameter Revision | Not Required | To be checked & revised as conductivity is very low. |
| Note : Tensile strength above 60000 PSI required in case of only force above 500 Kg/Cm2 | |||
