ZAMAK ZORES SECTION

ZAMAK Zamak

Metallurgy

An alloy of zinc containing aluminum, copper, and magnesium.

Z-BAR Z de

Metallurgy

A standard section whose straight section resembles the letter Z. The height of this rolled-iron product is at least equal than 38 mm; the flanges equal or not, are orthogonal to the web but directed in opposite direction one of the other.

Z-CONTRACTION OF CROSS SECTION FACTOR Coefficient de striction Z

Metallography

A ratio that concerns the tensile tests on steel test bars. The Z-contraction of the cross section factor is the ratio, expressed as a percentage of the initial section of the change of section after breaking of this initial section.

Z-GRADE Qualit Z

Metallurgy

The grade of the sheet metal and universal beam plates that have guaranteed levels of ductility in their thickness directions.

ZINC Zinc

Metallurgy

A white or bluish metal, resistant to corrosion. Syn. with SPELTER

ZINC BATH Galvin

Metallurgy

A bath of molten zinc used to galvanize ferrous metal pieces.

ZINC PLATING Zingage; Electrozingage

Metallurgy

1. An operation which consists in covering something with zinc.

2. A technique of applying a protective coating on a steel piece with a zinc film. The zinc plating can be carried out by various processes which are galvanization, electrolysis, sherardizing, or metal spraying with the gun. The types are:

   • plating by gun ( le zingage au pistolet) ( Schoop or Schori process), which consists in depositing a coat of zinc on a steel surfaces suitably prepared (by sanding or shot blasting),...
