ASTM B833-20(2025)

Annotation of standard text ASTM B833-20(2025) :

This specification covers zinc and zinc alloy wire used to deposit zinc coatings by thermal spraying (metallizing) for the corrosion protection of steel and iron. Zinc and zinc alloy wire provided under this specification is intended for use in oxy-fuel and electric arc thermal spraying equipment. The zinc used to manufacture the wire shall conform to the requirements for high grade zinc (Z15001) or special high grade zinc (Z13001). The wire shall conform to the chemical requirements for aluminum, cadmium, copper, iron, lead, tin, antimony, silver, bismuth, arsenic, nickel, magnesium, molybdenum, titanium, and zinc. The wire shall be clean and free of corrosion, adhering foreign material, scale, seams, nicks, burrs, bends or kinks which would interfere with the operation of thermal spraying equipment. The wire shall uncoil readily and shall be a continuous length per spool, coil, or drum. Splices or welds are permitted, provided that they do not interfere with the thermal spray equipment or coating process.
