Immersion in a liquid bath, such as molten lead or fused salts, held at an assigned temperature.
An alloy of copper and 2%-3% beryllium with nickel or cobalt, which shows remarkable age-hardening properties and good electrical conductivity; often used in electrical switches and springs.
A vertical shaft-type smelting furnace in which a hot air blast is used for producing pig iron.
Semi-finished products, hot rolled from ingots.
A mill used to reduce ingots to blooms, billets, slabs, sheet-bar, etc.
A copper-zinc alloy yellow in color; known as “High Brass” or “Two-to-One Brass.”
Joining metals by fusion of nonferrous alloys that have melting points above 800°F but lower than those of the metals being joined.
Bright Annealed Wire:
Steel wire bright drawn and annealed in controlled nonoxidizing atmosphere furnace.
A process of annealing usually carried out in a controlled furnace atmosphere so that surface oxidation is reduced to a minimum and the surface remains relatively bright.
Brinell Hardness Test:
A common standard method of measuring the hardness of certain metals by which the smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure or load. The diameter of the resulting indentation is measured by a special microscope.
A tendency to fracture without appreciable deformation.
An alloy of copper and tin.
A thin ridge or roughness left by a cutting operation such as in metal slitting, shearing, blanking or sawing.
Joining two edges or ends by placing one against the other and welding them.
