Engineering Callouts By Specification

ASTM B700 Electrodeposited Coatings of Silver for Engineering Use (Supersedes the Cancelled QQ-S-365)

• Type 1 – 99.9% minimum purity
• Type 2 – 99.0% minimum purity
• Type 3 – 98.0% minimum purity
• Grade A – Matte finish
• Grade B – Bright finish
• Grade C – Bright finish achieved by polishing
• Grade D – Semi-bright finish
• Class N – No supplemental anti-tarnish treatment
• Class S – With supplemental anti-tarnish treatment (Often Called “Tarniban”)
• NOTE:  You will want to call out the Spec, Thickness, Type, Grade, and Class.  An example would be “Silver Plate 0.001″ Thick Per ASTM B700, Type 1, Grade B, Class S”.

AMS 2410 Plating, Silver, Nickel Strike, High Bake

• Indicate the plating thickness

AMS 2411 Plating, Silver, For High Temperature Applications

• Indicate the plating thickness

AMS 2412 Plating, Silver, Copper Strike, Low Bake

• Indicate the plating thickness

QQ-S-365 D (Cancelled, superseded by ASTM B700 Above)

• Type I – Matte finish
• Type II – Semi-bright Finish
• Type III – Bright finish
• Grade A – With supplementary anti-tarnish treatment
• Grade B – Without supplemental treatment

Notes on Solderability and Tarnish-Resistance: Silver plating with chromate-type supplementary dips for tarnish resistance, like Tarniban, have a low contact resistance in the order of 300 to 400 micro-ohms per square inch. Solderability of the silver plate must be checked with a rosin-core solder.

Notes on Corrosion Resistance: For applications where corrosion protection is important, the use of an electro-deposited nickel undercoat is very advantageous.

Notes on Undercoating: 

• Silver plating on steel, zinc and zinc-based alloys should have an undercoat of nickel over copper.
• Silver plating on copper and copper alloys should have a nickel undercoat. When a nickel undercoat is not used on copper and copper alloy material, and other metal substrates where a copper undercoat is employed, should not be used for continuous service at a temperature in excess of 300 F (149 degrees C). Adhesion of the silver plating can be adversely affected due to the formation of a weak silver and copper inter-metallic layer.
