ASTM B607-21(2026)

Annotation of standard text ASTM B607-21(2026) :

This standard contains the requirements for autocatalytic nickel boron alloy coatings deposited from aqueous solutions without the use of external electric sources. The specification classifies the hard, uniform, microporous, and limited corrosion protection coatings as either Type 1 or Type 2 depending on the boron content. Both the physical and mechanical properties of the coatings such as density, hardness, stress, and melting point also vary with the boron content. In general, these coatings are not heat treated to maintain solderability.
