    Al-Zn Alloy Coated — BARO METAL

    The density of a 55% Al-Zn coating layer is lower than that of zinc coating, increasing the surface per ton by approximately 1~3%. Superb paintability. Adhesiveness between the coating layer and paint is superior to galvanized steel plates. Excellent workability. The level of workability is identical to that of galvanized steel sheet.

although other additions can be used; for example, the 5% aluminum alloy used for coating steel contains cerium and lanthanum. Early die casters had great problems in avoiding brittle castings until the cause of this defect was determined. Nowadays, the regular production of 99.99+ % zinc gives die casters a good

When should you use galvanized steel or zinc plated steel

Mar 09, 2011 · Both methods add a protective layer of zinc to the steel. Zinc protects the steel by sacrificing itself – called a “sacrificial anode”. When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2)

The coating finds application in screws and other light fasteners, light switch plates and other small parts. Materials for use in moderate or severe applications must be chromate conversion coated. The coating is entirely pure zinc, which has a hardness about one-third to one-half that of most steels.

Zinc/Aluminum Coatings for use with Structural Fasteners

Zn/Al coatings are relatively thin and uniform compared to traditional zinc coatings, however, many factors can influence the need for oversizing the nut thread to allow for the thickness of the coating. These include production dimensional limits, tool wear, actual coating thickness, coating thickness

95% zinc / 5% aluminum alloy), two aluminum based alloys (100% aluminum, 89-95% aluminum / 5-11% silicon alloy), and the terne coating (85-97% lead / 3-15% tin alloy). In 2004, there were approximately 85 hot-dip lines in North America, each of which could apply at least one of the seven coatings listed above. Electrogalvanizing

Welding of Coated Steels :Total Materia Article

When galvanized steel is arc welded the heat of the welding arc vaporizes the zinc coating in the weld area. This is because the boiling point of zinc (1600°F, 871°C) is below the melting point of steel (2800°F, 1538°C). The zinc volatilizes and leaves the base metal adjacent to the weld.
