Ag Nano System Provides all Gold and Silver Plating and Nano- Sliver like Gold Plating Processes   For Hard and Soft Gold Application (RACK AND BARREL PLATING)

Gold's hardness is measured on the Knoop scale , which tests the microhardness of brittle and thin materials. Commonly, gold is broken into two categories; hard and soft gold, each having their own unique applications. When choosing a gold plating service, figuring out whether to use hard or soft gold can be tricky. Here is a summary of the key differences between the two and common applications they are used in:

Hard Gold

·         Is an alloy of 99.7% gold and 0.3% of a hardening agent, most commonly either nickel or cobalt.

·         Gold plating is used as an electrical or electronic contact finish because it is a noble metal that does not oxidize or chemically react in corrosive environments.

·         Has a Knoop hardness between 130 – 200 and is used where electrical conductivity (especially very low current applications), solderability and/or corrosion resistance are important design requirements.

·         When compared to soft gold, hard gold proves superior contact wear resistance.

Soft Gold

 

·         Soft gold, also referred to as pure gold, is naturally soft because it has little to no grain refiners or additives to make the deposit hard.

·         Soft gold is 99.9% pure gold and has a Knoop hardness between 91-115.

·         It is pliable and is easier to solder than hard gold.

·         Soft gold is typically used in lead frame wire bonding applications and high reliability solder applications where hard gold would not be appropriate.
