Non-ferrous metal powders
a brief description of
Metal powders are amorphous mass of fine particles. Particle size, they are classified into: ultrathin (grain size ≤ 0,5 mm), very thin (0.5 — 10 microns), thin (10 — 40 microns), medium (40 — 150 mm), coarse (0.15 — 0.5 mm).
The shape of powder particles are divided into:
— Fiber, which have the greatest length on dlinniku;
— Flat, which have a small thickness;
— Equiaxed with the same dimensions in all directions.
metal powders have flowability, compressibility, bulk density. The fluidity depends on the beats. weight metal particles parameters, their shape, surface smoothness and is characterized by the rate of passage of a certain volume of powder through the minimum diameter of the hole. The better flowability, the more uniform and faster mold fills. The reduced turnover are rough particles of complex shape. Compressibility — a powder under pressure ability to acquire and retain a predetermined shape it. The more complex the shape of the particles and higher plasticity of the metal, the better compressibility. Bulk density — is the weight of loose powder located in the unit volume. It depends on the packing density of the powder particles and the volume proportion of metal. Heavy metal powders give the most dense products and the best press, which is important in the manufacture of machine parts. From powder to the small bulk density are obtained highly porous products.
Iron powder. The size of grains is divided into four groups: very small (OM), small (M), medium and big © ®. Iron powders are denoted marks: PZH4S, PZH2K etc., where «RV» means — iron powder, numeral:. 1, 2, 3, 4, 5 by means of chemical group. composition, and the letters «S» and «K» means a group on the grain. Modern industry produces the following powders of non-ferrous metals: nickel (PNE2, PNE1, PNK2 and PNK1), copper (PM, PMA, PMS2, PMS1), tin (ON), cobalt (PC1, PC2), silver (PS1, PS2), etc. metal powders of alloyed steels and carbon steels, stainless and high speed steel is also produced, bronze, brass and other alloys.
