Costs
Today, the cost of reinforcing particles is highly variable, with a downward trend in prices. For example, a pound (= 0.454 kg) of particles can vary from 2 to 40 Canadian dollars, depending on the nature and size of the particles, whereas a pound of processed aluminum (finished parts) used to cost only 1 to 2 dollars, depending on the alloy and, above all, the quantity. We need to keep a close eye on the price of aluminum, which...
