1. titanium gold: titanium is a rich metal with low density, high hardness and strong corrosion resistance. Therefore, titanium gold is mostly used in aerospace, medical and other fields, and is one of the key materials for manufacturing high-end products such as airplanes, missiles and rockets.
2. Platinum: Platinum is another rare precious metal with less reserves and higher price. Compared with titanium gold, platinum is harder, more stable and less susceptible to oxidation corrosion. Therefore, platinum is mostly used to make luxury goods such as jewelry and watches, and it is also one of the main raw materials of automobile catalysts.
Generally speaking, titanium and platinum mainly refer to these two metal alloy materials, which are light gold in color.
