The highest strength to weight mateirals
Lightweight Polymer Fasteners
One of the best methods to save considerable weight is to replace metallic fasteners with lightweight, metal-like polymer fasteners. Recent developments in polymer technology have finally produced lightweight polymers that can rival metals in may of their physical and mechanical properties. Taking weight into consideration, polymers such as lightweight PEEK Extreme and PAI (Torlon®), can provide specific strengths that exceed that of metallic fasteners.
Lightweight Titanium Fasteners
One property that stands out when compared to other metal fasteners is that titanium fasteners, especially titanium grade 5 fasteners, have the highest strength-to-weight ratio that is commercially available. This makes titanium fasteners ideal for applications that require both lightness of weight and excellent strength such as oil & gas (down-hole), military and sporting goods.
The chart below can be used to compare the properties of our lightweight, metal-like polymer fasteners with the properties of metallic fasteners.
