There were times when wearing simple steel-framed glasses was the most ordinary thing. Times have changed, but we still can select glasses, made in a classic manner from high-quality steel or from metal. The range of different metals is pretty wide. Metal frames are made of aluminium, titanium and iron. Derivatives of these metals are brass and stainless steel. Alloys include copper, nickel, and galvanised bronze based on brass. Copper alloys can contain tin, lead and beryllium. Nickel alloys may contain copper, brass and iron. Each of these metal materials has its individual set of properties and special aesthetic appeal. Aluminium frames are lightweight, but not very durable. Neat thin frames from stainless steel are reliable and strong. Titanium frames do not cause allergies, they are very lightweight and durable. In general, metal frames look very minimalist and subtle, but they are distinguished for their durability and flexibility if compared with plastic frames. Metal framing gives more chances to extend your glasses' life after a string of falls due to their wonderful impact proof option. If you are aimed at a stylish and exclusive look, metal frame glasses will optimally fulfil your desire.
