Aluminum Metal Spinning

Aluminum is an ideal material for metal spinning, offering a unique combination of properties that provide significant advantages in both manufacturing and end-use applications.

• Cost-Effective for Prototyping and Production: The tooling for aluminum spinning is sometimes less expensive than for processes like metal stamping—often just a fraction of the cost. This makes it the ideal choice for prototypes, new product development, and low-to-medium volume production runs where minimizing upfront investment is critical.
• Enhanced Strength-to-Weight Ratio: The metal spinning process, a “cold-working” technique, realigns the grain structure of the aluminum. This work-hardening effect significantly increases the material’s tensile strength, resulting in a finished part that is stronger and more durable than one made via casting or deep drawing.
• Seamless, High-Integrity Construction: Spun parts are formed from a single piece of aluminum, creating a seamless component with no welds. This monolithic construction is inherently stronger and can withstand higher pressures, making it perfect for applications like tank heads and pressure vessels.
• Inherent Corrosion Resistance: Aluminum naturally forms a protective oxide layer, making it highly resistant to rust and corrosion without the need for secondary treatments like painting. This is a major advantage for parts used in outdoor, marine, or humid environments.
• High Malleability and Design Freedom: Aluminum’s high ductility allows it to be formed into deeper, more intricate shapes than harder materials like steel. This gives designers greater freedom to create complex contours and geometries.
• Lightweight and Abundant: As a lightweight alternative to steel, aluminum reduces shipping costs and is ideal for applications where weight is a critical factor, such as in the aerospace and automotive industries.

Metal Craft Spinning & Stamping specializes in spinning aluminum of different sizes and alloys. Our aluminum products can be polished to the best standards to fulfill the needs of commercial industries. These alloys are the most preferred for aluminum spinning:

• Aluminum 1100-O: This commercially pure-grade aluminum alloy is made of 99% aluminum. This soft alloy has a lower strength but offers excellent formability, making it ideal for intricate shapes and deep-drawn parts where strength is not the primary concern.
• Aluminum 3003: This non-heat treatable alloy is made up of manganese, iron, copper, and small amounts of other elements. It is about 20% stronger than 1100 and is preferred for its moderate strength, excellent workability, and corrosion resistance.

Metal Craft Spinning & Stamping can spin aluminum with various thicknesses, ranging from 0.040 to 0.135 inch.

Aluminum metal spinning creates round, axially symmetric shapes like cones, tubes, hemispheres, parabolas, and cylinders, which are applicable in many contexts. Some examples of aluminum spun parts include:

• Funnels
• Drums
• Lighting
• HVAC
• Roofing
• Decorative components
• Electronic device parts
• Furniture
• Appliances
