Copper and its alloys

Copper

Copper is a plastic metal of pinkish red color. Primary copper depending on the purity is divided into M1, M2, M3.

Copper rolling

Rods

Rods (round, square, hexagon) cold-deformed (drawn ), hot-deformed ( extruded) manufactured in accordance with the requirements of GOST 1535-91 of copper grades ML , MLR , M2, M2P, M3, M3R according to the GOST 859.

Rods are available in soft, semi-solid, solid forms.

 

Tapes

Cold-drawn copper tape is manufactured in accordance with the requirements of GOST 1173-93 copper grades ML, MLR, M2, M2P, M3, and M3R according to the GOST 859.

Depending on accuracy of manufacturing: normal accuracy in thickness and width; normal accuracy in thickness and increased accuracy in width; normal accuracy in thickness and high accuracy in width; increased accuracy in thickness and normal accuracy in width.

 

Wire, tires

Copper wire and tires are produced in soft and hard form according to GOST 434-78 from copper not below grade M1 according to GOST 859.

 

Pipes

Copper pipes are manufactured in accordance with the requirements of GOST 617-90 of copper grades M 1, M1R, M2, M2R, M3, M3R with the chemical composition according to GOST 859, tombak brand L96 with the chemical composition according to GOST 15527, normal and high precision dimensional and random lengths from 1 to 6m.

Tubes can be cold drawn and pressed; soft, semi-solid, and solid.

 

Sheets and strips

Sheets and strips of copper are produced according to GOST 495-92 copper grades ML, MLR, M2, M2R, M3, and M3R according to GOST 859.

Cold-rolled sheets and strips made of normal and high manufacturing precision.

Hot rolled sheets are produced: width from 600 up to 3000 mm; length from 1000 to 6000 mm.

Strip is dimensional and random lengths from 500 to 2000 mm.

As material cold-rolled sheets and strips can be in soft, semi-solid and solid forms.

 

COPPER ALLOYS

Brass

Brass is an alloy of copper with zinc. With the introduction of the third, fourth or more components of brass called complex, or special, and they get the name of brass aluminum, iron-manganese brass, manganese-tin-lead brass, etc. Compared with copper they have a greater strength, corrosion resistance, elasticity and better process ability (casting, pressing, cutting).

Brass rolling

Rods

Brass rods are manufactured according to GOST 2060-90 drawn and pressed round, square and hexagonal sections of dimensional and unlimited length, in coils.

Accuracy of manufacturing: normal; increased; high.

Condition: soft, semi-solid, solid.

Special conditions: automatic, anti-magnetic rod with cut ends, soft state of high ductility, semi-solid state of high plasticity, hard state of high ductility, extruded state of normal plasticity.

 

Wire

Brass wire produced according to the requirements of GOST 1066-90 brass grades L80, L68, L63 and LS59-1 with the chemical composition according to GOST 15527 normal accuracy diameter.

As material brass wire can be made in soft, semi-solid and solid forms.

 

Tapes

Cold-rolled brass tapes are produced according to GOST 2208-91 brass grades L90, L85,L80, L68, L63, LS59-1, LMC58-2 with the chemical composition according to GOST 15527 in soft, semi-solid, solid, extra-solid and spring-hard condition.

Accuracy of manufacturing: normal accuracy in thickness and width, normal accuracy in thickness and increased accuracy in width, high thickness accuracy and normal accuracy in width.

Special conditions of performance: for stamping, antimagnetic, high accuracy on camber, with a normalized depth of the extrusion to withstand the bend test.

 

Pipes

Brass pipes are manufactured according to:

GOST 494-90 drawn, cold rolled and pressed: drawn and cold pipes from brass grades L63 and L68, extruded from brass grades L60, L63, LS59-1, LZhMC59-1-1 with a chemical composition according to GOST 15527 dimensional and random length from 1 to 6 m, in coils of length not less than 10 m.

Accuracy of manufacturing: normal; increased; high.

State: soft, soft with increased ductility, a quarter solid, semi-solid, semi-solid with increased ductility.

Special conditions: pipes of high accuracy, pipes of high accuracy in curvature, pipes antimagnetic.

GOST 21646-76 drawn and cold rolled. Dimensional and multiple dimensional lengths from 1.5 to 12 m from brass of the following grades: L70, L68, L070-1, LА77-2, LМSh68 -0,05, LАМShSh77-2-0,05 and LОМSh70-1-005 in accordance with GOST 15527.

Pipes, depending on the grades of alloys, are made in a soft and semi-solid state.

 

Sheets and strips

Brass sheets and strips are manufactured in accordance with GOST 931-90 from brass grades according to GOST 15527. The sheets are produced cold and hot rolled, stripes — cold-rolled lengths from 500 to 2000 mm, dimensional, multiple dimensional and unlimited lengths.

According to the state of the material, sheets and strips can be made in soft, semi-solid, hard, especially hard forms.

 

Bronze

Bronze is an alloy of copper (except brass and copper-nickel alloys) with tin (tin bronze) and copper alloys with aluminum, beryllium, manganese and other components, which are the main and in accordance with which of bronze be called. Compared to brass, bronze has the best mechanical and antifriction properties and corrosion resistance.

Rolled bronze, including:

Rods

Bronze rods: drawn (round, square and hexagonal), extruded (round) and hot rolled (round)  rods from tin-bronze are manufactured in accordance with GOST 1628-78 dimensional and random lengths ranging from 0.5 to 5m in semi-solid state.
