Watch material(1)

- Jan 25, 2018-

Stainless steel is the most widely used watch material, currently mainly 316 stainless steel and 304 stainless steel.Among them, 316 stainless steel is the surface shell material of high-grade wrist watch, because it contains molybdenum element, it is more resistant to corrosion than 304, and the price is more expensive than 304 steel, which is commonly referred to as "fine steel".

In general, homebred brand watch behind "stainless steel", majority is 304 stainless steel.In the process of use of 304 stainless steel, there are wear and a little rusting.

The new watch can't see the difference between the two.But 304 does not comply with European environmental requirements, so watches made in Switzerland or Europe are mostly 316 stainless steel.If there are 304 stainless steel watches, most of them are made and sold for other regions, or they belong to low-grade fashion watches.


An alloy, as the name implies, is a metallic substance that is composed of two or more metals or metals and non-metals by melting or sintering or by other means.The combination of various elements can improve the strength, hardness, abrasion resistance and corrosion resistance of the materials.The process performance was improved.

Folded titanium alloy

Titanium is the fourth largest in the earth's crust after aluminum, iron and magnesium.Pure titanium is a silvery white metal, melting point 1668 ° C, the density of 4.5 g/cm3.It is a light metal.Titanium chemical nature very lively, and easy with the oxygen in air, nitrogen, hydrogen and other elements interact, forming a very stable compounds, so everyday we talk about titanium generally refers to the titanium alloy.Titanium and its alloys are a new type of structural material developed in the late 1940s.Titanium alloy is made up of titanium and aluminum, vanadium, nickel, molybdenum and other elements, its main characteristic is better than high strength, corrosion resistance, good low temperature performance, in at the same time also has the special performance, such as superconductivity, memory, hydrogen storage.Its properties are very suitable for the environment of space and ocean, so titanium alloys are also known as aviation metals and Marine metals.

The watch industry has only recently begun to use titanium alloys, a cutting-edge high-tech material.At present, it is mainly concentrated in two kinds of watch brands.One kind is the sports brand or the sports series represented by panahai, tag, kunlun and Bohr.They looked at the advantages of low titanium density, high strength, no sweat erosion, and their watches were able to exert the advantage of titanium in motion.The other is the brand of technology, innovation and creativity, such as zenda, Dewitt, parma, and seiko.Their use of titanium is mainly due to their sensitivity to new materials and the courage and boldness of the first.Of course, as a watch to go into space, many of the family's series also use titanium alloy, a space metal that reflects China's own brand of science and technology.

Folded tungsten alloy

Tungsten alloys, based on tungsten, are added with a small amount of nickel, copper, iron, cobalt and other elements, known as high-gravity alloys, heavy alloys or high-density tungsten alloys.Because of its high density, high tensile strength, good absorption radiation ability, good electric properties, good corrosion resistance and oxidation resistance, are widely used in missiles, armor-piercing core and other weapons materials.Tungsten alloy has high hardness and good wear resistance, but because of its brittleness and ductility, only a few brands use tungsten alloy as the case and strap material.

Folded palladium alloy

Palladium is a kind of silver-white metal, it is the same as platinum group of precious metals, the value of natural and priceless.The price of palladium has increased tenfold over the past decade.Because of its tight and rare, coupled with a soft, ductility and plasticity is very strong, has many similarities with platinum, so in recent years by the jewelry and luxury goods makers, are being increasingly used in jewelry, watches and other luxury goods.In 2008, he tried to make a gold case with palladium, and the reaction was good.
