Non-ferrous metals do not contain iron, which means they won’t stick to a magnet and are naturally resistant to corrosion. This category includes copper, aluminium, brass, lead, zinc, stainless steel, and titanium. Non-ferrous metals command significantly higher prices per kilogram than ferrous scrap — copper and brass are particularly valuable. In New Zealand’s export market, non-ferrous materials dominate by dollar value even though ferrous dominates by tonnage. Separating your non-ferrous metals from steel before visiting the yard is one of the simplest ways to increase your payout at endless metals.
