|Materials|Copper Content in Square Wire|.
|-------|-------|.
|Pure copper|100%|.
|Copper-zinc alloy|85%-90%|.
|Copper-aluminum alloy|80%-85%|.
|Copper-nickel alloy|75%-80%|.
|Bronze|70%-75%|.
|Seamless Steel Tube|60%-65%|.
|Cold rolled steel sheet|40%-45%|.
From the above table, it can be seen that pure copper has the highest copper output rate of 100%, while cold rolled steel plate has the lowest copper output rate of 40%-45%. Square wire copper rate comparison table can help us more accurately determine the copper content in the material, so as to effectively control the quality of the material.
