Copper, brass, bronze reference

Are you interested in information about copper, brass and bronze? The supplier Evek GmbH offers to buy any non-ferrous metal at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimal.

Technical characteristics

Copper is characterized by good deformability and machinability in cold condition. Hot workable copper alloys can be produced in a wide temperature range from 900 to 650 °C.

DIN 1708 and 1726 designation Density, g/cm3 Cu, % Tensile strength MPa Tensile strength, MPa Elongation, % Relative elongation
C Cu 8,90 99,5 210 35...40 40
A Cu 8,87 99,1 230 40 35
E Cu 8,85 99,0 250 40...42 30

Pure copper is rarely used due to its scarcity. Copper alloys with zinc - bronze and brass - are more widely used in technology. Buy copper, brass and bronze offers the supplier Evek GmbH. The price from the manufacturer. Provide prompt delivery of products to any address.

Characteristics of brass

The minimum copper content in industrially used brasses is not less than 54...56%. The most common grades according to DIN 1708 and 1726:

Brass grade Cu, % Pb, % Fe, % Mn, % Sn, % Al, %
Ms72 71,5...74 ≤ 0,1 - - - -
Ms67 66...68 - - - - -
Ms63 62...65 0,5...2,0 0,20 - 0,30 0,10
Ms60 59...63 0,80 0,20 - 0,30 0,20
Ms58 56,6...59,5 3,0 ≤ 1,0 ≤ 1,0 - 1,0
Ms56 54,5...56,6 2,5 ≤1,0 0,5...1,0 0,5 -

The remainder of the brass composition is zinc. The first three grades are well processed in cold condition, the second three grades in hot condition. Brass is more durable than copper and can withstand higher operating loads.

Performance characteristics of bronzes

Alloys of copper, zinc with tin, silicon, etc. - Bronzes - well processed in hot and cold conditions, are characterized by high strength and chemical resistance under the action of aggressive media. Mechanical properties of the most widespread bronze alloys in the industry are listed in the table:

Bronze alloy designation according to DIN 1708 and DIN 1726 Delivery condition Tensile strength, MPa Elongation, % Relative elongation Brinell hardness
SnBz6F56 Emboldened 560 5 150...170
AlBz4F30 Annealed 300...380 50 50
AlBz5F42 Slightly annealed 420...540 15 110
AlBz9F56 Inhardened 560...700 5 160
SiBz2F34 Annealed 350 10 130
BeBz2F95 After cold pressing 950 3 200
