Engineering Summary

Silver 800 (DIN 17510 Ag800 / Werkstoff 2.3800 / French 2nd Standard) consists of 80.0% silver and 20.0% copper. Lying close to the silver-copper eutectic composition (71.9% Ag, melting at 779°C), this alloy exhibits high mechanical hardness, superior wear endurance, and a low melting range, making it the preferred composition for electromechanical breaker contacts, cutlery blades and tines, instrument gears, and wear-resistant hardware.

Silver 800 Documented Applications

›Industrial electromechanical breaker contacts and contactors
›Instrument gears, ratchet wheels, and pivot bushings
›Heavy-duty utilitarian flatware tines and structural cores
›Stamped watch cases, instrument housings, and hardware

Silver 800 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 60% relative to C36000. Clean chip evacuation; excellent machinability among silver alloys due to two-phase Cu-rich eutectic structure.

Weldability & Joining

Brazed with low-melting silver-copper-phosphorus or silver-copper-zinc fillers; close proximity of melting range (779°C-810°C) requires precise temperature control during joining.

Heat Treatment & Working Ranges

Annealed at 550°C to 600°C for 20 minutes; significant age-hardening response reaching up to 185 HV.

Forming & Cold Working

Lower cold ductility than high-fineness silvers; requires intermediate annealing for heavy reductions.
