Simonds Alloys
Points of Distinction
- Work Direct, Eliminate Middleman
- Fast Turn Around for Tight Deadlines
- Satisfaction Guaranteed
- Any shape. Any finish.
In addition to making custom alloys, we also make Simonds 73 alloy, 81 alloy and 83 alloy.
We not only melt your material, but we can also provide all of the ancillary operations — HIP, rolling, extrusion, heat treating, machining, etc. — the material may require. And since we can deliver your alloy in whatever final form you choose, you will always know whether your project is staying within your budget parameters.
