Blog Red Brass Material Profiles

Grade

• MTEK 844 (C84400) and MTEK 85-5-5-5 (C83600) Red brasses

Description

• General utility alloys where reasonable strength and non-corrosive properties are demanded.  

Mechanical Properties of Red Brass – Why select this material

• Relatively light loads.
• Good lubrication is possible.
• Excellent machinability.

Applications – Frequent uses

• Air and gas fittings, pipe fittings
• Faucets
• General hardware fittings
• Lightly stressed gears

Grade

• MTEK 85-5-5-5 (C83600) and MTEK 844 (C84400)

Description

• Medium duty red brass.
• Properties between the two alloys do not vary much, but C83600 is often more expensive because of higher tin content.

Properties – Why select this material

• C84400 is a variation of C83600 in that zinc and lead have replaced part of the copper and tin. The results are a reduction in cost and a small reduction in strength.
• Due to the alloying adjustments, there is a large reduction in the ability of C84400 to wear well with steel, and it is rarely used in a bearing application.

Applications – Frequent uses

• Plumbing-ware and fittings.
• May be used in bearing but only in where adequately lubricated.
