How to Tell Difference Between Bronze and Brass in CNC

What Is Brass?

Brass is a popular metal alloy you see in everyday items. People mix copper and zinc to make it. This blend gives brass its unique traits.

Composition of Brass

Brass mainly has copper and zinc. The mix can vary from 55% to 95% copper. Zinc fills the rest, sometimes with small amounts of other elements like lead.

This mix makes brass easy to shape. You can adjust the recipe for different needs.

Common Types of Brass

There are many types of brass. Alpha brass has more copper and is soft. Beta brass has more zinc and is stronger.

Examples include admiralty brass for ships and cartridge brass for ammo casings. Each type fits specific jobs.

Why Use Brass in Projects?

You choose brass for its looks and ease of use. It shines like gold and doesn’t rust easily. In CNC service, brass machines smoothly, saving time.

What Is Bronze?

Bronze is an ancient metal still used today. It combines copper with tin mainly. This creates a tough alloy for demanding tasks.

Composition of Bronze

Bronze has copper as the base, with 5% to 20% tin. Some types add phosphorus or aluminum.

Phosphor bronze, for example, includes phosphorus for extra strength. These additions change how bronze behaves.

Common Types of Bronze

Bronze comes in varieties like phosphor bronze and aluminum bronze. Phosphor bronze resists wear well.

Aluminum bronze handles salt water without corroding. You pick the type based on your project’s needs.

Why Bronze Stands Out

Bronze lasts long in harsh conditions. It fights corrosion better than many metals. For  CNC加工サービス in marine parts, bronze is a top pick.

Key Differences in Composition

Brass and bronze both start with copper. But their add-ins set them apart. Brass uses zinc, while bronze uses tin.

This swap changes everything from color to strength. Zinc makes brass brighter and cheaper. Tin makes bronze harder and pricier.

Variations exist too. Some brass adds lead for better machining. Bronze might include phosphorus for springs.

Physical Properties: How They Stack Up

You can spot brass and bronze by looks. Brass is golden yellow. Bronze is reddish brown.

Brass melts at lower temperatures, around 900°C. Bronze needs more heat, up to 950°C.

Density differs slightly. Bronze is denser at 8.7 g/cm³ versus brass at 8.4 g/cm³. These traits affect how you use them.

Brass vs Bronze: Metal Comparison

Mechanical Properties: Strength and Durability

Bronze wins in strength. It has higher tensile strength, often 500-800 MPa. Brass ranges from 300-500 MPa.

Brass is more ductile. You can bend it without breaking. Bronze can be brittle if not alloyed right.

For wear resistance, bronze shines in bearings. Brass suits fittings that need shaping.

Corrosion Resistance and Environmental Factors

Both resist rust, but bronze excels in saltwater. That’s why ships use bronze parts.

Brass handles fresh water well but can dezincify in acids. Add tin to brass for better resistance.

In polluted air, bronze holds up longer. Choose based on your environment.

Cost Analysis in 2026

Costs fluctuate, but bronze is pricier. In 2026, brass averages $6,000-$8,000 per ton. Bronze runs $7,000-$9,000 per ton.

Why the difference? Tin costs more than zinc. Processing bronze takes extra steps.

For small projects, the gap might be $1-2 per pound. Factor in longevity to see true value.

業界を超えたアプリケーション

You find these metals in many fields. Let’s break it down.

Brass in Everyday Use

Brass makes musical instruments like trumpets. Its sound quality is top-notch.

In plumbing, brass fittings last long. The automotive industry uses brass for radiators.

Bronze in Tough Environments

Bronze sculptures endure outdoors. Think of ancient statues still standing.

In the marine industry, bronze propellers fight corrosion. Aerospace parts use bronze for bushings.

CNC Machining Applications

Both work well in CNC. Brass cuts easily for intricate designs. Bronze needs slower speeds but holds tolerances.

In the electronics industry, brass connectors conduct well. Bronze springs in devices resist fatigue.
