Technical specification of products

Superhard gold patent

Earlier, Jony Ive, Apple's vice president of design, said in an interview with the Financial Times that Apple invented a new ultra-hard 18K gold material, which can effectively solve the durability problem of watches.

The author of the Financial Times also speculated on its description, claiming that "Apple uses new technology to combine gold molecules more closely to achieve high hardness", but this view was later overturned by the editor of Ars Technica.

In fact, through the industrial design patent applied by Apple, we can see that Apple uses a special gold production process, which involves mixing gold powder and ceramic powder, and then heating and compressing them to form a harder and more scratch-resistant material than ordinary gold.

However, "ceramics" is just a vague term. As can be seen from its patent, the description of raw materials is more than two lines, including boron carbide, diamond, titanium nitride, aluminum ferric silicate, silicon carbide, aluminum nitride and so on, which is very complicated.

In the manufacturing process, the key point is to build the prototype with this porous ceramic material and fill it with gold material. Simply put, a metallurgist constructs a multilayer ceramic, then injects gold into it for fusion, so that gold molecules are inserted between ceramic molecules, and then compresses and heats it until the metal and ceramic become solid substances.

In the end, the stunning 18K gold Apple Watch body was formed, which is also a process equivalent to "hand-customized" luxury goods.
