What Is Brass?

Brass is a metal made mainly from copper and zinc. The amount of copper in the mix determines its colour, strength, and scrap value.

Because copper is a high-value metal, the more copper brass contains, the more it’s usually worth at scrap yards.

This is where yellow brass and red brass differ.

What Is Yellow Brass?

Yellow brass is the most common type of brass you’ll find in homes and construction sites.

🔹 Composition:

• Around 60–70% copper

• Higher zinc content

🔹 Colour:

• Bright yellow or gold-like appearance

🔹 Common Sources:

• Door handles

• Taps and faucets

• Brass valves

• Plumbing fittings

• Decorative hardware

Yellow brass is widely used because it’s strong, corrosion-resistant, and affordable to produce.

💰 Scrap Value of Yellow Brass

Because yellow brass contains less copper than red brass, it generally sells for slightly lower prices in the Brass scrap recycling market.

However, clean yellow brass (free from plastic, steel, or rubber attachments) still commands a good rate at Scrap metal yards Perth.

What Is Red Brass?

Red brass, sometimes called gunmetal or rose brass, contains more copper than yellow brass.

🔹 Composition:

• Around 80–90% copper

• Lower zinc content

🔹 Colour:

• Reddish or pinkish tone

🔹 Common Sources:

• Old plumbing pipes

• Water meters

• Fire sprinkler heads

• Marine fittings

• Industrial valves

Because of its higher copper content, red brass is more corrosion-resistant and often used in heavy-duty plumbing and marine environments.

💰 Scrap Value of Red Brass

Red brass usually pays more per kilogram than yellow brass.

Why?
Because copper is more valuable — and red brass contains more of it.

If you separate red brass from yellow brass before visiting a Scrap metal Perth facility, you’ll almost always receive a higher payout.

How Scrap Yards Identify Brass Types

Professional Scrap metal yards Perth use several methods to determine brass type:

1. Visual inspection – Colour difference is often obvious.

2. Spark testing – Different metal compositions produce different sparks.

3. XRF analysers – Advanced machines measure metal composition instantly.

At West Coast Metals, experienced staff ensure fair classification so customers receive accurate pricing for their Brass scrap recycling materials.

Why Sorting Brass Increases Your Profit

Many people make the mistake of mixing yellow and red brass together. When you do this, scrap yards may pay the lower yellow brass rate for the entire batch.

Here’s how to maximise your payout:

✅ Separate red and yellow brass

✅ Remove steel screws and attachments

✅ Remove plastic or rubber parts

✅ Keep your scrap clean and dry

Clean, sorted brass always earns better returns at Scrap metal Perth facilities.

Market Demand in Perth

The demand for brass remains strong due to:

• Ongoing construction projects

• Plumbing upgrades

• Infrastructure development

• Export demand

With Perth’s steady growth in construction and renovation, Brass scrap recycling continues to be profitable for tradespeople and businesses.

Because red brass contains more copper, its value often moves closer to copper price trends. That’s why it typically holds stronger pricing in the scrap market.

Which Brass Should You Focus On?

If you’re in plumbing or demolition, red brass is more valuable and worth separating carefully.

If you handle mixed household fittings, you’ll mostly deal with yellow brass — but clean material still pays well.

For large quantities, even small price differences per kilo can significantly increase your total earnings.
