We have dedicated more than 20 years to refining our proprietary aluminum process for three hard to pour aluminum alloys: 850, 852, and 443. We supply aluminum tubes and rings rough machined to the exact dimensions you require to help cut down on your machining costs and minimize any excess material. The three aluminum alloys we utilize in our foundry allow us to manufacture castings with superior machinability, and lubricity to parts made from other materials like plastics and AL6061. OEMs looking for AL6061 – T6 manufacturers could benefit from a conversation with one of our aluminum casting experts about the benefits of using the AL850, AL852, or AL443 alloys.
850, 852, & 443
These alloys are commonly used to produce bearings, bearing housings, and labyrinth seals. They have excellent bearing qualities and good compressive yield strengths. Alloys 850 and 852 both have excellent machinability.
Supplied in the T5 or T101 condition if required.
Aluminum Castings for Labyrinth Seals, Bearings, and Bearing Housings
Quality Labyrinth seal manufacturing depends on the machinability of the alloy used as well as the ability of the manufacturer to design the part to tight specifications. Erie Bronze and Aluminum is the go-to aluminum casting supplier of motor and compressor OEMs for manufacturing rough machined castings for labyrinth seals, bearings, and bearing housings. Our rough machined aluminum castings generally follow these specifications:
- 1”-21” O.D. with a maximum length of 13”
- 21”>26” O.D. with a maximum length of 7”
- 26”>31” O.D. with a maximum length of 6”
- 31”>37.5” O.D. with a maximum length of 5”
- The inside diameter is machined to your specification.
