All products we supplied can meet ASTM, JIS, EN and GB standards, with strict quality control and full traceability.

High-purity C10100 copper tube, oxygen free copper tube is a tubular product made from high-purity copper with a copper content of 99.9% or higher. It is widely used in HVAC, refrigeration, plumbing, heat exchange, electrical, and industrial applications due to its exceptional thermal and electrical conductivity, corrosion resistance, and long service life.

Kepai innovated the production process and developed oxygen free high conductivity tellurium copper with independent intellectual property rights. With high corrosion resistance, extremely low oxygen content, good cold-working and hot-working ability, easy-cutting, pretty high electrical and thermal conductivity

C17200 beryllium copper provides the highest strength of all available copper-beryllium alloys. It has electrical and thermal conductivity considerably greater than other high-strength copper alloys with an ultimate tensile strength that can exceed 200 ksi (1380 MPa)

C17510 copper-nickel-beryllium alloy, also known as CuNi2Be, beryllium bronze and spring copper, is a copper alloy with 0.2–0.6% beryllium, 1.4-2.2% Nickel and sometimes other elements.

C18150 chromium-zirconium copper (chemical formula CuCrZr) is a copper-based alloy reinforced with chromium (0.1%-1.5%) and zirconium (0.02%-0.6%). It possesses high electrical conductivity, high strength, and resistance to high-temperature softening, and is widely used as a substitute for materials such as beryllium copper, becoming a core material in fields such as welding, molds, and aerospace. 

C14500 tellurium copper has good cold and hot working properties and can be processed by forging, casting, extrusion, drawing, and stamping. This allows C14500 to be processed into various profiles and special-shaped materials such as plates, sheets, rods, wires, and tubes

Oxygen-free Copper, whose English name is oxygen-free copper, refers to pure copper that contains no Oxygen and no residues of any deoxidizer. However, in actual production, due to process limitations, oxygen-free copper still contains very trace amounts of oxygen and some impurities. According to the standard regulations, the oxygen content of oxygen-free copper shall not exceed 0.003%, the total impurity content shall not exceed 0.05%, and the purity of copper shall be greater than 99.95%. According to the differences in oxygen content and impurity content, oxygen-free copper is further classified into No. 1 (C10100) and No. 2 (C10200) oxygen-free copper. The purity of oxygen-free copper No. 1 is as high as 99.97%, with the oxygen content and total impurity content not exceeding 0.003% and 0.03% respectively. The purity of oxygen-free copper No. 2 is 99.95%, and the oxygen content and total impurity content do not exceed 0.005% and 0.05% respectively.

Copper tellurium (TeCu) is a kind of high performance copper alloy containing trace tellurium, which is widely used in electronics, electric power, automobile manufacturing and other fields because of its excellent electrical conductivity, thermal conductivity and processing properties. As a high-end material in copper alloys, copper tellurium is a key material of choice in the industrial sector for its outstanding performance in improving equipment efficiency and durability.

Oxygen-free Copper (oxygen-free Copper, OFC) through vacuum melting + carbon reduction process, Oxygen content ≤0.001% (10 ppm), purity up to 99.99%, completely eliminate the interference of copper oxide (Cu₂O) on conductivity. Its electrical conductivity is ≥101% IACS, which is significantly improved compared with ordinary copper (100% IACS), and can reduce high-frequency signal transmission loss, which is suitable for 5G communication base stations, satellite RF components and other scenarios.
