What is equivalent to C28000 brass?
The alloy C28000 brass is directly and universally equivalent to the Chinese standard alloy H62.
Beyond this primary equivalent, it corresponds to several other major international designations:
In the European (EN) standard, it is known as CuZn37 or the material code CW508L.
In the Japanese (JIS) standard, it is designated as C2800.

What is the composition of brass c28000?
Brass UNS C28000 (equivalent to H62) is primarily 60.0-63.0% Copper and 37.0-40.0% Zinc. It is a low-lead brass with a maximum lead (Pb) content of 0.30% (typically much lower). Iron is limited to a maximum of 0.07%, and total other impurities do not exceed 0.15%. This composition provides a strong, formable, and versatile general-purpose brass.

What is the difference between brass 260 and 280?
C260 plates and sheets are the most ductile of the brasses, and is used in greater quantity than any other copper-zinc alloy. C280 (Muntz) most important characteristic is its color, and is stronger, harder and more rigid than brasses of lesser zinc content.

What is the machinability rating of C28000 brass?
C28000 brass has a fair machinability rating of around 40% on the standard scale where free-cutting brass C36000 is rated at 100%. It produces continuous chips.

What is C28000 brass used for?
C28000 brass is widely used in architectural hardware (hinges, locks), electrical connectors, heat exchanger components, plumbing fittings, decorative trim, and various stamped parts.

Can C28000 brass be welded?
Yes, C28000 brass can be welded and brazed using appropriate techniques and filler metals designed for copper alloys, such as silicon-bronze or brass filler rods.

What is the density of C28000 brass?
The density of C28000 brass is approximately 8.43 grams per cubic centimeter (g/cm³), or 0.304 pounds per cubic inch (lb/in³).

Is C28000 brass corrosion resistant?
C28000 brass offers good corrosion resistance in atmospheric, fresh water, and many mild chemical environments. However, it can be susceptible to dezincification in specific stagnant or high-chloride waters.
