Description
Class: ERCuSi-A
AWS: A5.7
Conforms to Certification: AWS – 5.7 ASME SFA A5.7
Silicon Bronze: Tig Welding Process (GTAW)
| AWS Chemical Composition Requirements | |
| Cu = Remainder | Zn = 1.0 max |
| Sn = 1.0 max | Mn = 1.5 max |
| Fe = 0.50 max | Si = 2.8 – 4.0 |
| Al = 0.01 max | Pb = 0.02 max |
| Other = 0.50 max | |
Application
Use for welding of Silicon Bronze Copper, or Aluminum Bronze of low aluminum content. It can also be used for brazing malleable iron and light gauge steel.
Deposited Chemical Composition % (Typical)
Dependent on weld process
(Nominal) All Weld Metal Properties Requirements
Tensile Strength 50,000psi
Preheat / Interpass Recommendations
When working with silicon bronze base metal keep the inter-pass temperature below 65° C to minimize hot cracking. Base metals of cast iron may need a preheat of 315° C while copper may need 200-400° C.

Perfect
As they always have, Alex and the KO team have smashed it out of the park. So easy to buy what I need in the quantity I need to suit the scale of y business.
Cheers again mate.
