Ultra-Machinable 360 Brass Rods and Discs
- Yield Strength:
Inch sizes: 15,000 psi
Metric sizes: 23,000 psi - Hardness: See table
- Temper:
Inch sizes: H02 (1/2 Hard)
Metric sizes: 1/2 Hard - Heat Treatable: No
- Specifications Met:
Inch sizes: ASTM B16
Metric sizes: European Standard EN 12164
With the highest lead content of all the brass alloys, 360 offers the best machinability. Often called free-machining and free-cutting brass, it stands up to high-speed drilling, milling, and tapping operations with minimal wear on your tools. It’s commonly used for gears, pinions, and lock components.
Certificates with a traceable lot number are available for these products. Download certificates from ACTIVITY after your order ships.

Ultra-Formable 260 Brass Round Tubes
The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.
Tubes with 0.014" and 0.45 mm wall thicknesses allow you to create telescoping tubes; each tube fits inside the next larger size.

Machine Key Stock
Cut this square or rectangular key stock to length to create a straight machine key. Straight keys are the most common type of key. Machine keys are often the same material and as hard or harder than the shaft and other components with which they are used. To use a key as a sacrificial part, choose a softer key that will shear off when parts are exposed to excessive force, preventing damage to expensive equipment.
Steel key stock is an economical choice with good strength. 4140 alloy steel key stock has greater strength and toughness after hardening than carbon steel, making it useful for high-stress applications. Stainless steel key stock is more corrosion resistant than steel key stock. 304 stainless steel key stock offers a good balance of strength, corrosion resistance, and machinability. Slightly smaller than the size listed in the table, undersized stock is the choice when you need a slightly looser fit or when you have an inconsistent keyway. Use it when parts need to be taken apart frequently, such as for maintenance or prototyping.
Key stock that meets DIN 6880 conforms to DIN standards for undersized keys.
