Bronze rental GOST
The rumors of my death are greatly exaggerated, once joked mark TWAIN. Similar words can fend off the claim that «bronze age» ended in ancient times. Modern bronze alloys found a wide application in the twenty-first century.
General characteristics
The Foundation is considered to be of bronze copper and tin. But except these elements, the copper can contain aluminum, beryllium, zirconium and other elements. The chemical composition of bronze divided into tin-tin. Aside cast alloys and pressure treated. A distinctive feature of the bronzes is considered to be corrosion resistance, excellent processability, durability, low price.
Classification
Tin bronze contains more than 4% Sn, when casting give minimum shrinkage, which is extremely important for the production of quality castings. Aluminum bronze can contain up to 8% Al, it is easily bent, stamped, rolled in a cold state. All the bronze are wonderful corrosion resistance, mechanical strength and cheapness. One of the cheapest — silicon bronze. Bronze beryllium contains 2% Be and in addition the strength, corrosion resistance and excellent processability, has a high elasticity, and also the fact that when hitting other metal does not spark. The latter quality is especially important when working in hazardous conditions.
Dignity
The production of tin bronze man mastered at the dawn of its history. This alloy is corrosion resistance, low melting temperature, inexpensive production technology, excellent manufacturability. It is a plastic, biologically inert metal with good sliding qualities. It is easily punched, drilled, bent, cut, has excellent casting properties. Most bronzes (except aluminum) are easily welded and soldered with special solders. After the disposal of bronze goes for recycling and use. Numerous advantages make it very popular today.
Production
Chem. the composition of bronze alloys normalizes GOST 5017−74; 18 175−78; 493−79. Technical conditions of production — GOST 24 301−93. For the production of castings used centrifugal or chill casting. The weight of manufactured goods under the order can be from several grams to several tons. OOO «Electrocentury-steel» sells from stock the following types of bronze bars: round, tape, strip, wire, ingots, pipe, hex. Prices are the most affordable.
Marking
Bronze alloys are marked with the abbreviation Br, followed by capital letters of alloying elements and their percentages. For example, BRAF 10−1 — bronze tin-phosphorus, contains 10% tin and 1% phosphorus. Brocs-5−5-5 (tin bronze, alloy zinc, and lead),
Application
Construction, engineering, transport, energy, water etc. Wrought alloys are the basis of the liners, bushings, pins — corrosion-resistant and durable. Bronze rental well maintained in conditions of high pressure and temperature. Produce bronze bearings, valves, gears, nuts, gaskets, washers, bolts, bushings, shafts, springs. Well-spring in silicon bronze. Beryllium bronze does not spark when striking, which is very important in hazardous conditions. «Admiralty bronze» — is alloyed with zinc, is particularly resistant to corrosion in salt water, used in shipbuilding for the production of propellers and add-ons, etc. Aluminum bronze — lightweight, durable, high-tech relevant in the shipbuilding, automotive, aviation. Good electrical conductivity of bronze, important in the energy sector. Bronze cast candlesticks, stands for table lamps, household items, statues, monuments. Bronze is durable, items from it can serve several generations.
Assortment
Bronze bushing and liner. Apply to expendable parts. They are plastic, wear quickly, but at the same time protect more critical parts of the mechanisms. Being a consumable item, bronze extends the life of the equipment. The sleeve is produced from the brands: Brag, Bro5c5s5, Brotss 5−5-5, etc.
Bronze ribbon. It is produced of the brands: Bra7; Brb2; Pbnt; БрБ2м, БрБ2т; BRAF; BRAF 7−0,2; Brof 6,5−0,15; Broc4−3; Bross, PCMC; PCMC 3−1.
The sheet is characterized by sufficient hardness and strength, resistance to moisture and chemicals. good electrical and thermal conductivity, are widely demanded in many industries. Made from grades: Brh1, Áðõ1öð, ÌÍ2,5КоКрХ
Bronze wire. It is produced of the brands: Bramc9−2; Brahms 8,5−4-5−1,5; Brb2,5; Brb2; Bmhc 2,5−0,7−0,6; Brof6,5−0,4; Broc4−3; Brkmc3−1БрХЦрК; Brh0,7.
The rod is produced from manufacturing: Brainmc 9−4-4−1, Brams 10−3-1,5; Bramc9−2; Brb2; Broc4−3; Brkmc3−1; Brkmc3−1A;
The bronze pig is made from grades: Brazh9−4L; БрАЖ10−3; Brazhmc10−3-2; Brams 9−2, БрОС8−12, БрОЦС3−13−4, БрОЦС5−5-5; БрОЦС5−6-5.
