If it is to process metal materials, it depends on its hardness. Among many metal materials, stainless steel is the hardest, while cast iron is slightly inferior. The hardness of copper is lower than cast iron, and the hardness of aluminum is the lowest. Therefore, stainless steel should b...
The Mohs Hardness Scale is a standard that indicates the hardness of minerals. It was first proposed by German mineralogist Frederich Mohs in 1822.
The wear index for aluminum alloys in Type-III anodizing (depending of the alloy type) is clearly stated in the aforementioned section. Some companies of great recognition worldwide even provide the surface hardness for type-III (which is commonly C60-C70 Rockwell), but nothing about the type-...
When two or more pure metals are combined, it often leads to changes in the mechanical properties of the resulting metal. The most common changes include an increase in strength and hardness. For example, steel is an alloy of iron and carbon. The addition of carbon makes steel much harder ...
Hard anodizing is the process by which a hard anodic film on aluminum or its alloy is produced, the film hardness usually considered to be more than 300 kg/mm2 at 25 μm film thickness. A feature never exploited for anodic films is that the stress pattern around the identification shows ...
Relatively pure aluminium is encountered only when corrosion resistance and/or workability is more important than strength or hardness.Aluminium is a soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. ...
Al2O3-TiC cemented carbide. Made of aluminum oxide and titanium carbide, it has high hardness, strength, wear resistance and corrosion resistance, and is used to make cutting tools, molds, etc. In addition, according to different uses and processing requirements, cemented carbide can also be ...

In addition, the test does not provide us insight into the specific water quality issues, such as Elevated Hardness (mineral content in water), Salty Taste, or Corrosiveness (also called aggressive water, which is how water dissolves with other materials). Therefore, the total disso...
Titanium nitride is the barrier metal most commonly found in semiconductors. Chromium, tantalum, tantalum nitride and tungsten nitride also are used. Conductivity and hardness aren't the only two properties taken into account with a barrier metal; the thickness of the barrier metal also plays a ...
