Technical characteristics

CuAl9Fe4 is deformable bronze alloy (aluminium bronze). Manufacture is specified by GOST 18175−78 (chemical composition), GOST 1628−78 (technical conditions). CuAl9Fe4 contains aluminium (9%), iron (4%) in its composition. Chemical formula is CuAl9Fe4. Except for main alloying elements, there are present zinc, silicon, tin, phosphorus, plumb.


Ferrum refines grains and provides delay of recrystallizing. Zinc provides increasing of corrosion and technological properties. Silicon provides increasing of mechanical properties, heat resistance, corrosion resistance, recrystallization temperature. It also increases antifriction properties, resistance to low temperatures.

Alloy hardness: HB 10 -1 = 100 — 120 MPа

Point of melting = 1040°C

Sheet of CuAl9Fe4 grade possesses high anticorrosive, antifriction and mechanical properties. Bronze alloy of CuAl9Fe4 grade can be exposed to pressure treatment not only in hot condition but in cold condition as well.

Main properties

Hardness of CuAl9Fe4 is HB 10 -1 = 100 — 120 MPa.

Coefficient of friction in CuAl9Fe4 grade:

Coefficient of friction with lubrication — 0.004;

Coefficient of friction with lubrication — 0.18.

Special feature of aluminium bronzes are extra strength-to-density ratio and improving of mechanical properties after heat treatment. In order to improve strength characteristics, aluminium-iron bronze is exposed to age-hardening at a temperature of 250−300°С for 2−3 hours on completing thermohardening (t° 950°C). Aluminium-iron bronzes can be perfectly pressure-treated in cold condition. They are used in manufacture of worm screws, bushings, gears.


This alloy is used in manufacture of pin bushes, valves, valve seats for needs of mechanical and motor engineering. It is also used for casting of essential parts in aircraft industry; in a manufacture of valve, bushings, worms, gears, screw boxes that are exploited in marine shipbuilding at a temperature up to 250 °C.
