How to Sort Copper for Scrap with a Handheld XRF Copper Analyzer
Copper purity directly drives scrap price. Copper wire purity standards demand ＞99.90% Cu for electrical applications; alloyed or contaminated scrap typically fetches 30–50% less per tonne. Buyers specify copper grades based on precise purity, rejecting material with zi...Read more -
How to Determine Elemental Composition of Nickel Based Alloys?
Nickel-based alloys are engineered metals containing nickel as the primary element, often exceeding 50% by weight. Their microstructure enables exceptional mechanical strength, creep resistance, and oxidation stability up to 800°C. These properties make nickel-based allo...Read more -
0.4% Chloride Ruins Concrete—Is Your Steel Safe?
Chloride content in concrete directly accelerates corrosion of reinforcing steel, disrupting protective oxide layers and causing localized rust formation. Chloride concentrations exceeding 0.4% by mass of cement trigger corrosion of reinforcement, reducing structural dur...Read more
