Copper Aluminum Composited Fin Tube

Although the composited fin tube can be with base material such as carbon steel, 304/316 stainless steel, 90/10 copper-nickel, as well as other various different fin materials, none of these are as efficient or economical as copper/aluminum composited fin tubes.

The base copper tube (copper grade can be C12200, C70600, C44300, CuNi70/30, CuNi 90/10) is inserted into the aluminum muff tube, through rolling process, the fins are extruded out of the aluminum sleeve. Then ends fin will strip off from tube at customized length, cleaning, blast blowing, drying and then package.

The copper tube is produced according to ASTM (American Society of Testing Materials) and ASME (American Society of Mechanical Engineers) Standards.

The base copper tube standard is ASTM B75, ASME SB75, ASTM B111, ASME SB111

General Review on Copper Tube International Standards
