Brass is mostly an alloy made from copper and zinc. Sometimes, there are small amounts of lead, tin, or nickel in it. The mix of these elements changes how brass acts when you machine it. For example, if you use a cnc machine on brass, the right mix makes it easier and faster to work with. The table below shows the usual percentage range for copper and zinc in brass:
Component | Percentage Range |
|---|---|
Copper | 60% to 90% |
Zinc | 10% to 40% |
Lead helps make brass easier to machine. This is why people like to use brass for high-quality parts. Brass cnc machining gives you strong and accurate parts with good quality. You can trust brass machining for parts that need to be strong and made quickly.
Brass is mostly made from copper and zinc. The amount of each changes how brass looks and works.
Picking the right brass type is important. C360 is good for easy cutting. C260 is better for bending. This helps get better results when using CNC machines.
Brass is easy to shape and cut. It does not rust easily. It is strong. These things make brass great for many uses. It is used in cars and plumbing.
Adding things like lead, tin, or nickel can make brass better. These extras help brass last longer and be easier to work with.
Knowing what is in brass helps you choose the best kind. This means your project will turn out well and not cost too much.
You find that brass is mostly made from copper and zinc. These two metals give brass its main features. Copper gives brass a reddish color and helps with electrical conductivity. Zinc makes brass stronger and more elastic. When you change the amount of copper and zinc, you change how brass looks and works. If you use more copper, brass looks golden and is easier to bend. If you add more zinc, brass becomes brighter yellow or even grey-silver. The strength of brass goes up as you add more zinc, but it can become less resistant to corrosion. This is important when you choose brass for cnc machining brass projects because you want the right balance for your part.
Tip: The color of brass changes from reddish to yellow and then to grey-silver as zinc content increases. This helps you pick the right brass for your design.
You sometimes see other elements in brass. Lead is often added to make brass softer and easier for machining. Tin increases strength and hardness, which helps when you need tough parts. Nickel gives brass a silver color and can improve corrosion resistance. Manganese turns brass a warm chocolate-brown. Arsenic helps brass stay stable in certain environments. These extra elements change the properties of brass and help you get the best quality for cnc machining brass.
Lead makes brass easier to machine.
Tin boosts strength and hardness.
Nickel adds a silver color.
Manganese gives a brown shade.
Arsenic improves stability.
You need to know the proportion ranges of copper and zinc in brass. This helps you choose the right type for cnc machining brass. The table below shows common brass grades and their copper and zinc percentages:
Class | Copper (%) | Zinc (%) | Notes |
|---|---|---|---|
Alpha brasses | > 65 | < 35 | Malleable, golden color, good for cold working |
Alpha-beta brasses | 55–65 | 35–45 | Brighter, suited for hot working |
Beta brasses | 50–55 | 45–50 | Harder, stronger, hot working only |
Gamma brasses | 33–39 | 61–67 | Brittle, special uses |
White brass | < 50 | > 50 | Very brittle, sometimes called nickel silver |
When you select brass for cnc machining, you look at these ranges to match the properties of brass to your needs. High zinc content means more strength, but less ductility. If you want easy machining and high quality, you often choose brass with added lead and a balanced copper-zinc mix. This helps you get the best results in cnc machining brass and cnc brass machining.
Brass has many grades. Each grade has its own mix and features. You should know these differences before you pick brass for your project. JOC Machinery sells many brass grades for cnc machining and casting. Let’s check out three common brass grades. Their mix changes how easy they are to machine, bend, and resist rust.
C360 Free-Cutting Brass is a top pick for machining. It has copper (61.5%), zinc (35.5%), and lead (3%). Lead makes this brass simple to cut and shape. You can use cnc machines fast with this grade. This saves time and helps tools last longer. C360 gives smooth surfaces and strong parts. Many people use C360 for gears, valves, and electrical fittings.
Tip: Pick C360 Free-Cutting Brass for quick machining and good results.
C260 Cartridge Brass has about 70% copper and 30% zinc. You see this brass in bullet casings, plumbing, marine parts, and musical tools. The high copper makes it easy to bend and stops rust. You can shape this brass easily. It works well for deep drawing and forming jobs. JOC Machinery gives C260 to many industries needing strong and nice-looking brass.
Application Area | Description |
|---|---|
Ammunition Casings | Strong and resists rust |
Plumbing Fixtures | Lasts long and works well |
Marine Hardware | Stays good in wet places |
Musical Instruments | Great for sound quality |
C335 Free-Machining Brass has 62.5% copper, 36.5% zinc, and 1% lead. It is easy to machine, but not as much as C360. This grade is good for parts needing both strength and easy machining. You can use C335 for fittings, fasteners, and other parts needing quality.
You should match brass properties to your job. Here is a table with main brass features by grade:
Brass Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Hardness (HB) | Elongation (%) | Electrical Conductivity (% IACS) |
|---|---|---|---|---|---|
C360 | 345-450 | 110-210 | 80-100 | 20-30 | 25-30 |
C260 | 300-550 | 95-250 | 60-85 | 25-40 | 27-35 |
C335 | 350-450 | 120-200 | 75-95 | 18-28 | 26-32 |
C360 is best for easy machining and smooth surfaces.
C260 is great for bending and stopping rust.
C335 gives both easy machining and strength.
