Antifriction bronze. Brand
The company Electrocentury-steel offers at the best price from the manufacturer of antifriction bronze alloys. The supplier guarantees the quality of the metal ensures prompt delivery of products to the address specified by the customer.
Chemical composition of alloys
Antifriction bronze alloys are used as obtained by casting, and after the deforming processing. Often used bronze olovjannaja marks Br. ОЦС5−5-3 according to GOST 613, phosphor bronze Br. OF 1 at 211АМТУ and bronze bezalabernaya brands of Br. АЖ9−4, Br. АЖ9−4L and Br. АЖН10−4-4−4L. The composition of these alloys are given in the table:
|Br. АЖ9−4, Br. АЖ9−4L||-||8…10||-||-||2…4||-|
|Br. АЖН10−4-4−4L||-||9,5 11,0…||-||-||3.5 to 8.5…||-|
In bronze of Br. АЖН10−4-4−4L additionally contains 3.5…5.5% Nickel. The total number of metallurgical impurities should not exceed 0,75…2,7% (lower rates correspond to phosphor bronze).
The company Electrocentury-steel implements at affordable prices manufacturer of castings, forgings and metal products of all brands antifriction bronzes. Delivery of products is performed in a timely manner and at the address indicated by the customer.
The use of antifriction bronze alloys
Criterion of success use is the value of the marginal unit of effort and circumferential speeds at which the parts are operated. Most often there are the following options:
- Bronze made a crown wheel, which is paired with a steel worm or gear. It is advisable to use bronze alloys that contain aluminum and iron;
- Made from bronze liner bearing, the load on which does not exceed 100…150 MPa. In this case, it is advisable to use bronze alloys that contain aluminum and iron;
- Made of bronze liners and bushing sliding bearings that operate at contact loads up to 100 MPA and circumferential velocities not exceeding 2 m/s is Used alemannische bronze;
- Bronze is made especially responsible crowns worm wheels, bushings bearings and bushings, which are affected by contact pressure up to 200 MPa and the circumferential speed of 3 m/s is Used phosphor bronze.
To buy rolling, forging, casting of bronze anti-friction alloys at factory price offered by the company Electrocentury-steel. The supplier ensures prompt delivery of products to the address specified by the customer.
