What is the difference between ferrous and non-ferrous metal? Why is non-ferrous worth more per pound?
Non-Ferrous Metals do not contain Iron. They are non-magnetic and are more resistant to corrosion like rust for example, unlike ferrous materials. Metals like copper, brass, stainless steel and aluminum are used in plumbing to protect our water supply from contamination, this makes these metals more valuable and high in demand.
What does it mean if the metal I bring is called "dirty" or "heavy dirty"?
Dirty metal has either plastic, wood, cement, dirt, wire or other metals attached to it. Unless the foreign material is removed, the metal will be down-graded and bought for a lower price. For example, a metal such as aluminum that is free of nails, screws, plastic clips, and wood is considered clean and will be bought at a higher price.
Is all copper wire the same?
No, not all wire is created equal. We grade our copper wire by the percentage of copper in relation to the amount of insulated plastic or aluminum coating. We also consider whether the copper inside is solid or frayed. Our percentages run from, 35% copper present to 85% copper present.
Why are the prices different from the last time I brought metal?
Prices paid for metals are subject to change based on market value. Market value is determined by metal trading prices on the commodities market. For the latest pricing please call ahead at (604) 313-1887
