According to expert analysis, replacement of copper tubing in refrigerators and freezers is needed for the following reasons: first, by means of the innovation process to ensure that the material characteristics of the steel pipe meet the refrigerator/freezer refrigeration piping products' technical requirements; second is a huge cost advantage for home appliance manufacturers; third is enhancement of the strength of the internal spatial structure without increased difficulty of assembly.

many air conditioning manufacturers are struggling to find a new alternative refrigerant pipe, and for refrigeration pipes, the most suitable alternative to copper tube material is aluminium alloy, which is less than 30% copper, making the replacement of significant economic value.
