Copper Alloy Scrap (high grade)

Description

Product Overview
High-grade Copper Alloy Scrap consists of clean, uncoated, and segregated alloy solids with a verified copper base (brass, bronze, or cupronickel variants). It is primarily used by secondary smelters, rod mills, and master alloy producers as a charge material to replace virgin cathode and reduce melting energy costs. The key value proposition is its high net yield per ton and predictable chemistry, which stabilizes melt recipes. Strategically, this scrap enables buyers to lower carbon footprint while securing cost-advantaged copper units in a volatile primary metal market.

Key Specifications & Technical Characteristics

• Chemical composition: Cu ≥ 92% (balance Zn, Sn, Pb, Fe ≤ 1.5% total impurities)

• Purity level / Grade: ISRI code “Barley” / “Berry” equivalent – high-grade alloy scrap, no insulated wire, no shredder fines

• Physical characteristics: Mixed clean solids, cut size 5mm–300mm,色泽 copper-red to yellow-brass, bulk density 2.5–3.5 t/m³

• Packaging options: 1.5 MT shrink-wrapped bales, 2 MT steel strapped bundles, or bulk loose in open-top containers

• Shelf life: Indefinite if stored dry; no oxidation risk for melt use

Core Industrial Applications

• Primary industries: Secondary copper smelters, brass rod manufacturers, foundries, and chemical copper sulfate plants

• Specific use cases: Charge material for vertical continuous casting of brass ingots; dilution feed for oxygen-free copper production; alloy correction in electric arc furnaces

• Performance advantage: Lower melting point (1,050–1,080°C) vs. virgin cathode (1,085°C) – reduces energy use by 12–18% per ton melted

• Cost advantage: 8–15% price discount to LME Grade A cathode with equivalent copper recovery (≥96%)

Competitive Advantages

• Quality consistency: XRF-verified lot certificates; negative sorting for aluminum/sulfur contamination

• Supply reliability: 1,000+ MT monthly availability from dismantling and industrial fabrication offcuts

• Price competitiveness: Fixed formula based on LME copper minus treatment charge, no hidden fees

• Sustainability: 100% recycled content reduces CO₂ by over 65% vs. mined copper; eligible for green procurement credits

Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT

• Loading capacity: 25 MT per 20-foot container (baled) / 22 MT per 20-foot container (loose)
