Cuprass (CuZnAl)

In order to increase the mechanical properties of brass, nickel, manganese, iron, tin or silicon elements can be added to copper, apart from zinc.
In these alloys called special brass, the total amount of additional elements does not exceed 5%.

Categories: ,
Description

These elements increase the tensile strength without much effect on the elongation properties.

These alloys containing multiple elements are called high strength brasses. Corrosion resistance is excellent.

We have, three types of high-strength brasses are produced and composition-specific production can be made.

 

Cuprass 1: It has a moderate slip feature. It is used as a compression nut in rolling mills and screw presses, as well as in ship propellers. (Hardness 120 HB)

Cuprass 2: It is a hard material with high strength. Construction parts, machine parts, etc. operating under static load. is also used. (Hardness 160 HB)

Cuprass 3: It is a high strength hard brass. It is used in the manufacture of bearings, worm screws and gears operating at high and low speeds. (Hardness 190 HB)

APPLICATION AREAS

APPLICATION AREAS

Bearings operating at low and high speeds

Worm screw and gear manufacturing

In sliding and putel bearings such as slide, slide and press bush

Working with high stroke

As gearbox reinforcement pin in heavy vehicles

Ship parts and propellers due to their high corrosion resistance

It can be used instead of brass and bronze in the holders of spot welding electrodes.
