In the procurement of metal products, it is often encountered in the case of aluminum circles. The cost calculation of such products is not complicated. Let's take a brief introduction to the aluminum circle as an example.
Material cost = theoretical weight * theoretical aluminum ingot unit price
Theoretical weight = 3.14 * radius * radius * height (thickness) * density 2.73
Theoretical aluminum ingot unit price = spot aluminum ingot unit price * (1 + X)
a. Pay attention to the conversion problem of unit of measure and unit of weight during the calculation process;
b.X is the loss part of the process of processing aluminum ingot into aluminum circle, which is different according to the difference between industry and product. If there is no standard quantitation, you default to 3%.
Processing costs vary by material and product and can be negotiated at the initial stage of cooperation.
