Silver 835 Processing & Fabrication

Machining, joining, forming, and thermal processing ratings cataloged from the cited authoritative technical reference.

Source: ASTM International & ISO / DIN Standards Technical Committees

Machinability

Rated at approximately 55% relative to C36000. Good machinability with crisp edge retention; produces shorter curling chips.

Weldability & Joining

Brazed with standard Ag-Cu-Zn filler metals. Requires active fluxing to dissolve heavy copper oxidation.

Heat Treatment & Working Ranges

Annealed at 550°C to 620°C for 20 minutes, followed by water quench. Rapidly age-hardens at 280°C to 300°C.

Forming & Cold Working

Moderate cold ductility; can be punched and stamped with adequate punch clearances.
