Brass rental (DIN, EN)
general characteristics
Depending on the chemical composition of the brass is divided into simple and complex. Copper-zinc alloy with a small amount of impurities called double or simple. Composite alloys additionally contain, for example, lead, and manganese, which facilitates machining. Aluminium improves the overall strength, but reduces the ductility, phosphorus — increases the hardness, nickel — increases wear resistance and chemical resistance. Tin can increase corrosion resistance, but also increases the brittleness. High casting characteristics of the alloy of silicon forms. Iron increases the quality and fluidity of the details in the process of casting and provides fine-grained structure of rental.
dignity
Brass compared with copper have higher strength, better corrosion resistance and castability. They are flexible, easy to deform under pressure, any available types of machining brass parts are easy to assemble. Besides this alloy is cost less than bronze or copper.
Classification
According to the degree of hardness brass is divided into hard, Semisolid, soft and extremely hard alloys. This division depends on the magnitude of pressure required for cold working of metal. It varies for brass, and the range of 30 — 64 kg / mm 2. Red and yellow brass vary depending on the proportion of zinc. What it is, the alloy becomes yellow. Brass hire is subdivided into the following types: circle, strip, sheet, wire, tube and hexagon.
application
Brass rolled produce sanitary ware and decorative items for interior decoration. The instrument is Barometric and condenser pipe liner of chemical apparatus, printing matrix. Brass made for mechanical engineering bearings and bushings, engine cooling system. Complex alloys with the addition of tin demand in shipbuilding and different chemical inertness. They are also used when creating a modern military equipment and ammunition.
Production
The price list of brass rolled — over 200 profiles section from 7 to 40 mm. Round bars let out measuring length and multiple dimensional. The production includes horizontal casting, broach, followed by calibration, thus achieving improved accuracy parameters and optimizes the operation of automatic metal processing lines. The most popular brands: LS59−1 — «sypuchka» (40% zinc, 59% copper and 1% lead) and L63 — «jamming» (37% zinc and 63% copper)
The percentage of LS59−1 grade (GOST 15 527−2004)
| Zn | Cu | Fe | Pb | Sn | Sb | P | Bi | Si + Sn | Impurities |
|---|---|---|---|---|---|---|---|---|---|
| 37,05−42,2 | 57−60 | 0.5 | 0.8−1.9 | ≤0,3 | ≤0,01 | ≤0,025 | ≤0,003 | ≤0,5 | ≤0,75 |
The percentage of L63 grade (GOST 15 527−2004)
| Zn | Cu | Fe | Pb | Sn | Sb | P | Bi | Si | Impurities |
|---|---|---|---|---|---|---|---|---|---|
| 34,22−37,5 | 62−65 | ≤0,2 | ≤0,07 | --- | ≤0,005 | ≤0,015 | ≤0,002 | --- | ≤0,5 |
Manufacture of bars in t. H. The circular or hexagonal profile (GOST 2060−90), sheets, wire, tubes and belts. The basis of heat transfer elements are generally «boiler» marks L68 tube (68% Cu and 32% Zn) (21 to GOST 646−76). For topical shipbuilding LO62−1 brass (62% Cu, 37% Zn and 1% Pb), with excellent corrosion resistance. LS-59 — is the basis of hexagonal tubes, hexagonal rods. Production of cold-hex range LS59−1 normalized GOST 2060−90 two types of accuracy: high and normal. Brass rods produce a semi-solid, soft and hard. They are the basis of hardware. Round drawn bars can be 3 accuracy levels: elevated, normal and high.
