This is in an update on our previous material guide dated 2016. This material guide will help you understand our capabilities as a metal spinning business and will help you in your decision making for future projects within your business.
It is important to understand that there are a number of limiting factors which can have an affect on your required dimension. A common example involves certain material thickness resulting in varying limitations with regards to the dimensions of component or finished piece. The diameter can also in turn have limitation on the thickness of the material. Another limiting factor is the material choice itself which will affect both the dimensions and thickness.
Below is a list of materials with their assigned minimum and maximum Diameters and Thicknesses that can be successfully spun within our factory.
|Material||Minimum Diameter (mm)||Maximum Diameter (mm)||Minimum Thickness (mm)||Maximum Thickness (mm)|
|Aerospace Grade Alloys||30||2221||0.9||1|
|Marine Grade Alloys||30||2221||0.9||1|
|Mild Steel CR4||30||2221||0.7||6|
|304 Grade Stainless Steel||30||2221||0.9||4|
|316 Grade Stainless Steel||30||2221||0.9||4|
|4003 Grade Stainless Steel||30||2221||0.9||4|
Understanding these properties will help determine which material is best suited for a specific design. This material guide will help you understand our capabilities as a metal spinning business.
|Oxidises quickly creating resistance to corrosion by air, water and chemicals.||Requires specialised processes in order to be welded|
|Easily coloured by anodising and holds paint very well.||It is abrasive to tooling|
|Better conductor of Electricity than copper.||It is expensive, even more than steel.|
|Recyclable||Prone to severe spring back.|
|Has the highest strength-to-weight ratio of any metal.|
|Great choice for applications avoiding magnetism.|
|Lightweight, lighter than steel.|
|Inexpensive to Ship|
|More Economical than Brass or Steel|
|Its durable. It is an alloy of Copper and Zinc||Brass with high zinc content is often hard and brittle.|
|Resilient||If higher copper content it will be susceptible to corrosion.|
|Great for heavy-duty use.||Not as good an electrical conductor as Copper|
|Can withstand high temperatures||Low melting point|
|More malleable than Steel or Iron, easily machined|
|Good electrical conductor|
|Flexible, its properties can be changed when aluminium is added for example|
|High Electrical Conductivity||Expensive|
|High Thermal Conductivity||Loses its colour easily due to heating|
|Great for electrical components||Easily scratched|
|Very ductile and malleable||Corrodes at a negligible rate in air, water and deaerated acids|
|High corrosion resistance|
|Sustainable and recyclable||Dangerous in pipes as it can leech led|
|Corrosion Resistance||High initial costs|
|Less maintenance – no shrinking or cracking|
|Readily available||Low strength-to-weight ratio|
|Easy to machine||Rusts|
|Easy to weld||Cannot be improved via heat treatment|
|Low costs||Low corrosion resistance|
