272 Brass (C27200) – Composition, Properties, And Uses

What is 272 Brass ?

ASTM B36 is a valuable alloy of brass that is widely used in the manufacturing and engineering sectors. Primarily made up of zinc, copper, and tin, Brass Alloy 272 offers a remarkable range of benefits to industrial producers. It has superior resistance to corrosion and abrasion, is highly malleable for various applications and processes, and its strength remains intact over time. On top of that, Brass 272 is significantly more affordable than other metal alloys. This makes it ideal for industries looking for ways to reduce costs while still upholding quality standards. As such, it's no surprise why Brass 272 has become an essential material in producing parts of all shapes and sizes in many industries around the world.

272 Brass Composition

Brass 272 is an alpha-beta brass that contains 72% copper and 28% zinc. It also contains trace amounts of lead (<0.2%), iron (<0.3%), arsenic (<0.01%), manganese (<0.3%), and phosphorus (<0.04%). Together these elements give it superior malleability compared to other alloys with similar compositions, such as 70/30 brass or 60/40 brass.

UNS C27200 Brass 272 Chemical Properties

ASTM B36 Brass has excellent corrosion resistance when exposed to various types of corrosive environments such as salt water, sulfuric acid, hydrochloric acid, etc., making it an ideal material for many applications where corrosion resistance is paramount. The alloy also has good electrical conductivity, making it useful for electrical wiring applications.

Brass 272 Physical properties

C27200 Brass is an alloy of copper and zinc with excellent physical properties. It has high electrical conductivity, corrosion resistance, cold formability, and a neutral to a slightly yellowish tint. In particular, it provides superior heat conduction performance, allowing it to be used in a variety of applications across many industries. By combining the properties of copper and zinc together into one alloy, Brass 272 offers both strength and durability while remaining cost-effective. Its workability makes it possible to achieve intricate designs in products that benefit from its superior characteristics. As a result, engineers and designers often specify this alloy for challenging applications requiring superior performance coupled with affordability.

272 Brass Mechanical Properties

The mechanical properties of brass 272 depend on the heat treatment options used during processing. The most commonly used heat treatments are stress relieving (annealing) and aging (aging). Stress relieving makes the material more ductile, while aging increases hardness and strength without compromising ductility or malleability too much. Age hardening can be done at temperatures ranging from 400°F to 600°F (204°C to 315°C). Machining is possible on Brass 272 with standard tooling, but cutting speeds should be kept low so as not to damage the surface finish or cause excessive wear on the tools themselves.
