API 5CT: From raw materials to products before delivery, flattening test, tensile test, impact test, tensile test and other relevant tests shall be conducted. API 5L: The production cost of stainless steel seamless pipe is obviously higher than that of welded pipe due to the micro alloying heating treatment process.

C24000 brass with a nominal composition of 80 % copper and 20 % zinc approaches the mechanical properties of CuZn30 but with corrosion properties only slightly inferior to CuZn15. This alloy has a color between yellow and golden red and finds distinctive uses in decorative trim applications.

UNS C12000 copper has 95% IACS conductivity, low residual phosphorus, and high embrittlement resistance. It has a good electrical conductivity and excellent welding and soldering properties. It can be formed excellent, either hot or cold.

C23000 brass is the most durable of all metals for commercial water Bar in the practical price range. Excellent for its resistance to dezincification and season cracking for which the high copper brasses are known. Moderate strength and good retention of spring properties.

C22000 Commercial Bronze is a copper alloy that is nominally composed of 90% copper and 10% zinc. Though, due to the fact that it has more zinc than tin, this alloy can actually be categorized as brass. It gets its reddish color from the high amount of copper.

Alloy C21000 is a yellow brass. With a small zinc addition, the alloy is stronger and more durable than pure copper, while exhibiting excellent formability, corrosion resistance, and solderability amongst the brasses. C21000 finds use in applications from connector components to fasteners.

General Description C12200, Phosphorus deoxidised copper, has been made weldable and brazeable by deoxidising with phosphorus. It is widely used as flat products and tubing, especially where it is to be welded or brazed.

Copper wires conduct electrical currents that power our homes and electrical appliances we use every day. Copper wire is the preferred conductor for many electrical applications because of the high conductivity of copper, which contributes to its optimal performance.
