Figure out where is titanium different from aluminum, we can easier to find which alloy to use for your machining parts.
1. Cost
Definitely, aluminum is a more cost-effective metal for CNC machining, while titanium parts simply last longer. High cost of extraction and fabrication limits some applications of titanium.
2. Weight and strength
Titanium is heavier than aluminum, but its inherent strength means that you need less of it.
3. Application
– Titanium is often used in aerospace, aircraft and spacecraft, satellite components, fixtures, and brackets, medical applications like dental implants, surgical instrumentation, marine industry including hip hulls, submarines, and other structures exposed to seawater, and applications require heat resistance.
– Aluminum products applications including bicycle frames, fishing reels, small boats, and vehicle frames, molds for plastics and tooling, aircraft frames, electrical conductor, heat sinks, and applications require high thermal conductivity.
4. Machinability
Aluminum is easy to process in CNC turning, milling, drilling and more, while titanium is hard to work with.
5. Density
Titanium’s higher density means that strength-to-weight ratios for the two metals tend to be similar.
6. Appearance
Aluminium comes in a silvery white color and varies from silver to dull grey depending on the surface roughness, while titanium has a silver surface.
