Technical specifications
Bronze Br AKHN10−4-4 (the closest foreign analogue is the alloy CuAl10Ni5Fe4) is a tinless plastically deformable bronze, in which there is an increased percentage of aluminum, nickel and iron. This material is characterized by high enough strength and corrosion resistance. The development of corrosion processes that occur in liquid and gaseous media is hampered by a strong oxide film that forms on the surface of the products during their operation. Bronze grade BR АЖН10−4-4 (CuAl10Ni5Fe4) is characterized by a low coefficient of sliding friction in conditions of excessive lubrication of the contacting parts. Corrosion resistance indicators are fully preserved when the products are used in marine and chlorine-containing water.
Urgency of application
Wire, circle and rod of bronze БР АЖН10−4-4 (CuAl10Ni5Fe4) are used in the manufacture of valve seats, mixing units, plunger tips, steam traps in steam boilers of power plants and water dechlorination plants, movable components of general machine-building designation (shafts, cams, gears, cogs crowns), which function under conditions of high relative pressures and slip velocities. Bronze bronze of the brand BRAZHN 10−4-4 (CuAl10Ni5Fe4) is also produced by propellers of low-tonnage vessels and some types of fasteners.

Assortment and application features
In accordance with the technical requirements of GOST 1628−78, the bronze rod and the bronze circle Br AHNH-10−4-4 are produced in the range of diameters from 5 to 40 mm, the wire from 0.08 to 12 mm.
This bronze can be forged: the beginning of deformation — at a temperature of 920 0 C, the end — at a temperature not lower than 800 0 C. The alloy can not deform in the cold state. Weldability — satisfactory, limited (only under a layer of flux).
