Through a couple of weeks of effort, we are ready to deliver the ASTM B111 UNS C61300 Aluminum Bronze Tubes to our Italian Customer. They will be used for heat exchangers, the dimension is: OD 10MM x WT 0.89MM x Length 1,500MM. We also can produce UNS C11000, UNS C44300, UNS C68700, UNS C70600, UNS […]
Finally, we successfully delivered the precious metal sheet to our Saudi Arabia customer. They will be used for manufacturing the Pressure Vessels for the Petrochemical plant. Standard: ASME SB265, ASME SECTION II Part B Grade: 2 Dimensions: 3x1000x1000mm 10x2000x2500mm 12x1600x3000mm 20x1000x1200mm
Ammonia is an important raw material for the manufacture of nitric acid, ammonium salt and amine. Ammonia is gas at room temperature and can be liquefied under pressure. Most metals such as stainless steel, aluminum, magnesium, titanium, etc. have excellent corrosion resistance to ammonia gas, liquid ammonia and ammonia water, except copper and other copper […]
The heat treatment of Cu-Be alloy is mainly solid solution annealing and aging hardening. Unlike other copper alloys whose strength is obtained only by cold machining, wrought copper beryllium is obtained by cold machining and hot aging hardening processes up to 1250-1500 Mpa. Aging hardening is often referred to as precipitation hardening or heat treatment. […]
As we all know, copper and steel (iron) are two different metals. The thermal conductivity of copper is 7-11 times greater than that of ordinary carbon steel, and it is difficult to reach the melting temperature. When copper is melted, its surface tension is 1/3 less than that of iron, and its fluidity is 1-1.5 […]
The common heat treatment methods of copper alloy are homogeneous annealing, stress – free annealing, recrystallization annealing, solid solution and aging treatment. In order to prevent oxidation during processing, save the cost of pickling and obtain a bright surface, it is allowed to anneal copper alloy strip, wire and coil tube in a protective atmosphere […]
In last article, we discussed the question”What’s Beryllium Copper”, as well as we know, Beryllium Copper is also known as beryllium bronze, is a type of precipitated hardened copper alloy with beryllium as the main alloying element. Its density is 8.3g/cm³, 0.2~2.75% beryllium making its strength is twice that of other copper alloys. Beryllium copper […]
A drill bit is a cutting tool with circular cross-section that create holes in an alloy materials. The commonly used drill bits mainly include spiral bit, flat bit, center bit, deep hole bit and bush bit. Reaming and countersink drill bits may not be used to drill holes in solid material, but they are traditionally […]
KOVAR alloy is an Iron-Nickel-Cobalt alloy with a density of 8.36g/cm3 and a linear expansion coefficient between 20 and 500℃ equal to that of glass and ceramics. Most metals cannot be sealed with glass because their thermal expansion rate is different from that of glass and the joints are liable to break when cooled. The […]
INVAR alloy, the abbreviation of Invariability, composed of64% Fe, 36% Ni and little other elements such as S, P, and C, has a very low linear expansion coefficient under 100 ℃, also known as low expansion steel, it’s firstly found by French physicist C.E.GuialmeI by 1896. The NVAR trademark was originally held by the French […]
