Tin Brass Plate has high corrosion resistance, good mechanical properties, in cold, hot pressure processing good, can be used on the ship corrosion-resistant parts and steam, oil and other media contact parts and pipes. Brass row good mechanical properties, electrical conductivity, low thermal conductivity, corrosion resistance, a tendency to corrosion cracking, corrosion-resistant important parts and weak electrical industrial parts. H90 HIGH-PRECISION BRASS ROW CHARACTERISTICS AND SCOPE OF APPLICATION: strength than copper (but in ordinary brass, it is the lowest) , good electrical and thermal conductivity, in the atmosphere and fresh water with high corrosion resistance, and good plasticity, easy cold, hot pressure processing, easy welding, forging and tinning, no stress corrosion cracking tendency. The hot working temperature is 850 ~ 950 °c, the annealing temperature is 650 ~ 720 °C, and the low temperature annealing temperature is 200 °C.

(2) composition

Brass plate is an alloy of copper and zinc. Brass that consists of only copper and zinc is called brass. "brass is often used to make valves, water pipes, connecting pipes for air-conditioners and radiators. " If it is made of more than two elements, it is called special brass. Such as lead, tin, manganese, nickel, iron, silicon composed of copper alloy. Brass has strong wear resistance. Special brass is also called special brass, it is high strength, hardness, chemical corrosion resistance. There are also more prominent machining mechanical properties. Seamless copper tubes made of brass are soft and wear-resistant. Brass seamless tube can be used for heat exchanger and condenser, low temperature pipeline, submarine transportation pipe. Manufacture sheet, strip, bar, pipe, casting parts, etc. . Copper in 62% ~ 68% , strong plasticity, manufacture of pressure equipment. Brass can be divided into ordinary brass and special brass according to the kinds of alloy elements in brass. The brass used for pressure processing is called deformed brass.

(3) purpose

Can do a variety of deep drawing and bending manufacturing force parts, such as pins, rivets, washers, nuts, tubes, barometer, screen, radiator parts. It has good mechanical properties, good plasticity in hot state, good plasticity in cold state, good machinability, easy welding and welding, corrosion resistance, is a common brass widely used variety.

2, the brass row has the strength to be high, the plasticity is good, is suitable cold, the hot processing weldability and the corrosion resistance is good, good mechanical properties, good plasticity in hot state, good machinability, weldability and corrosion resistance;

What is the meaning of Red Copper Bar

Red Copper row also known as Red Copper is pure copper, because of its color for the purple-red and named. See Copper for various properties. Red Copper is pure industrial copper, its melting point is 1083 °C, no isomeric transformation, the relative density is 8.9. The mass of the same volume is about 15% that of ordinary steel. Because of its rose-red color, the surface of the oxide film formed after the purple, it is generally known as copper. It is copper containing a certain amount of oxygen, so it is also known as copper containing oxygen. It is not necessarily pure copper, but is sometimes added a small amount of deoxidization or other elements to improve the material and function, and is therefore also classified as a copper alloy. According to the composition, Chinese red copper bar can be divided into four types: ordinary copper bar (T1, T2, T3, T4) , oxygen-free copper (TU1, TU2 and high purity, oxygen-free copper in vacuum) , oxygen-free copper (Tup, Tumn) , special copper (as-copper, tellurium-copper, silver-copper) added with a small amount of alloying elements. The conductivity and thermal conductivity of Red Copper are second only to silver, and are widely used in making electrical and thermal conductivity devices. Copper row in the atmosphere, sea water and some non-oxidizing acid (hydrochloric acid, dilute sulfuric acid) , Alkali, salt solution and a variety of organic acids (acetic acid, citric acid) , has good corrosion resistance, used in the chemical industry. In addition, red copper row has good weldability, can be cold, thermoplastic processing into a variety of semi-finished products and finished products. In the 1970s, the output of copper bars exceeded the output of all other types of copper alloys. With good corrosion resistance, used in chemical industry. (3) the difference between brass and brass is that brass is harder than copper! Red Copper, also known as red copper, that is pure copper, red copper and brass in the color and quality are different! In fact, a look at the color to understand, as the name implies! Red Copper is harder in quality than brass, almost the same in weight, pure copper is also called red copper, its density (7.83 g/cm3) , melting point is 1083 °C, non-magnetic, has good conductivity, thermal conductivity and anti-corrosion, toughness, the density of brass (8.93 g/cm3) is used in the lining of mechanical bearing Bush, the density of wear-resistant "brass" is higher than that of red copper. Brass row luster beautiful, has good technology and mechanical function, electrical conductivity and thermal conductivity, in the atmosphere, fresh water and seawater corrosion resistance, easy cutting and polishing, weldability and cheap. Commonly used in the manufacture of conductive, thermal components, corrosion-resistant structural components, elastic components, daily hardware and decorative materials, and other widely used. Generally speaking, the cutting function of brass bar is better than that of Red Copper Bar (red copper bar is easy to stick knife) . Copper Strip is pure copper, pure copper color is orange or rose red, but exposed to the air will be oxidized to purple, so called Copper Strip. Brass row is Cu-Zn alloy, containing about 80% copper. Hardness than copper bar, but poor electrical and thermal conductivity.
