Custom Metal Spun Hemispheres

At Columbia Metal Spinning, we specialize in metal spinning of spheres and hemispheres in materials such as brass, copper, aluminum, carbon and stainless steel, as well as a wide range of exotic metals.

For 60+ years, we’ve been providing precision metal spun products to customers in industries such as aerospace, automotive, oil and gas, and numerous other industries requiring tight tolerance metal hemispheres. What sets us apart from our competition is the sheer number of materials that we can work with. Most metal spinning providers are limited to common metals such as aluminum, steel, brass and perhaps one other material. At Columbia Metal Spinning we recognize customers have needs and requirements that go beyond basic choices. As a result, we have grown our capabilities and invested capital in state-of-the-art equipment and metal spinning systems which allow us to accommodate almost any metal spinning requirement.These advanced capabilities allow us to deliver metal spun products from 1” to 38” in diameter and a depth of 1” to 20”, all to precision tolerances ±.005” to ±.060”, depending on specifications. Our manufacturing efficiency allows for a cost-effective product whether purchasing 1 or 10,000 hemispheres.
