Metal spinning is a metal forming process that uses a lathe and a spinning tool to shape metal into various forms. It is a versatile process that can be used to create a wide range of products, from simple cones and cylinders to complex shapes such as domes, hemispheres, and parabolic reflectors.
When choosing a metal for metal spinning, there are a number of factors to consider, including:
Ductility: The metal must be ductile enough to be deformed into the desired shape. Ductile metals have a high yield strength and a low ultimate tensile strength.
Strength: The metal must be strong enough to withstand the forces of spinning. Strong metals have a high ultimate tensile strength.
Workability: The metal must be easy to work with. Workable metals are soft and easy to cut and machine.
Corrosion resistance: The metal must be resistant to corrosion if it will be exposed to corrosive environments.
Cost: The cost of the metal is also an important factor to consider.
Some of the most common metals used for metal spinning include:
Aluminum: Aluminum is a lightweight and ductile metal that is easy to work with. It is also corrosion resistant. However, aluminum is not as strong as some other metals, such as steel.
Brass: Brass is a strong and ductile metal that is also corrosion resistant. It is more expensive than aluminum, but it is also more durable.
Copper: Copper is a strong and ductile metal that is also a good conductor of heat and electricity. It is more expensive than brass, but it is also more versatile.
Steel: Steel is a strong and durable metal. However, it is not as ductile as some other metals, such as aluminum and copper. Steel is also more expensive than aluminum and copper.
When choosing a metal for a specific metal spinning project, it is important to consider the requirements of the product. For example, if the product needs to be lightweight and corrosion resistant, aluminum may be a good choice. If the product needs to be strong and durable, steel may be a better choice.
Here are some additional tips for choosing the right metal for metal spinning:
Consider the final shape of the product. Some metals are better suited for certain shapes than others. For example, aluminum is a good choice for products with complex shapes, such as domes and hemispheres. Steel is a good choice for products with simple shapes, such as cones and cylinders.
Consider the thickness of the metal. The thickness of the metal will affect the ductility and strength of the product. Thinner metals are more ductile and easier to spin, but they are also less strong. Thicker metals are less ductile and more difficult to spin, but they are also stronger.
Consider the surface finish of the product. Some metals are better suited for certain surface finishes than others. For example, aluminum is a good choice for products with a polished finish. Steel is a good choice for products with a painted finish.
If you are unsure which metal is right for your metal spinning project, it is a good idea to consult with a professional metal spinner. They can help you to choose the right metal for your specific needs.
