Understanding brass scrap grades is essential for sellers, buyers, and recyclers to maximize value, ensure accurate alloy recovery, and trade confidently. Brass comes in a variety of industrial alloys, each with distinct copper content, corrosion resistance, and market demand. This guide covers the key grading categories—Yellow Brass, Red Brass, and Admiralty Brass—and explains their differences, applications, and pricing considerations.
Through Scrap Trade, sellers and buyers can list, compare, and trade brass scrap transparently, ensuring compliance with Australian standards and global market expectations.
Overview of Brass Scrap Grades
Brass is a copper-zinc alloy with variable zinc content that influences strength, ductility, and corrosion resistance. Industrial scrap is generally classified into three major categories:
- Yellow Brass – Common domestic and industrial brass with lower copper content.
- Red Brass – Higher copper content, more corrosion-resistant, often used in marine and plumbing.
- Admiralty Brass – Tin-containing brass alloy, highly corrosion-resistant, primarily for marine applications.
Proper grading ensures accurate pricing and attracts verified buyers in domestic and international markets.
1. Yellow Brass Scrap
Composition:
- Copper: ~60–63%
- Zinc: ~37–40%
- Trace elements for corrosion resistance
Sources:
- Standard plumbing fixtures (taps, faucets)
- Electrical components
- Decorative fittings
Characteristics:
- Moderate corrosion resistance
- Good malleability
- High recyclability
Pricing & Market Demand:
Yellow brass is widely available and moderately priced, making it suitable for bulk domestic buyers.
💡 Sellers can increase value by removing plastic, steel, and non-metal attachments before sale.
2. Red Brass Scrap
Composition:
- Copper: ~85%
- Zinc: ~15%
- Optional small amounts of lead for machinability
Sources:
- Marine fittings and valves
- High-quality plumbing components
- Industrial valves and machinery parts
Characteristics:
- Excellent corrosion resistance, including seawater
- Higher copper content increases recovery value
- Stronger and more durable than yellow brass
Pricing & Market Demand:
Red brass attracts premium pricing due to higher copper content and industrial demand, especially for export and foundry use.
3. Admiralty Brass Scrap
Composition:
- Copper: ~70%
- Zinc: ~29%
- Tin: 1% (for enhanced corrosion resistance)
Sources:
- Marine-grade valves and propellers
- Shipbuilding components
- Offshore hardware
Characteristics:
- Tin addition provides dezincification resistance
- Highly corrosion-resistant in saltwater
- Considered premium marine alloy
Pricing & Market Demand:
Admiralty brass is highly sought after by marine equipment manufacturers and international foundries, commanding the highest scrap value among common brass grades.
Brass Scrap Grading Tips for Sellers
- Separate alloys: Don’t mix yellow, red, and Admiralty brass; buyers pay more for correctly graded material.
- Clean the scrap: Remove plastic, rubber, steel, and non-metal attachments.
- Document source: Especially for marine or industrial fittings, providing origin boosts buyer confidence.
- Weigh accurately: Bulk pricing often depends on precise weight and alloy verification.

Featured FAQs – Real-World Questions
What’s the main difference between yellow and red brass?
Red brass has higher copper content, better corrosion resistance, and commands higher pricing.
Is Admiralty brass worth more than red brass?
Yes, due to tin addition and its marine-grade corrosion resistance.
Should I separate brass by alloy before selling?
Absolutely. Alloy separation significantly improves pricing and buyer confidence.
Does cleaning fittings improve scrap value?
Yes, removing plastic, steel, and other contaminants increases per-kg offers.
Can graded brass scrap be exported?
Yes, especially when clearly documented and cleaned.
