How hard is cobalt?
It is soft in nature . Because of its dramatic color change and the ease of the hydration/dehydration reaction, "cobalt chloride" is used as an indicator for water in desiccants. Its formula is CoCl2.6H2O
What metal is harder tungsten or cobalt?
Tungsten is harder than cobalt. Tungsten has a higher hardness on the Mohs scale than cobalt, making it more resistant to scratching or deformation.
What does the phrase cobalt steel mean?
Cobalt steel is a form of high-speed steel containing a significant proportion of cobalt. M-35 (5% cobalt) and M-42 (8% cobalt) are common cobalt steel alloys. See http://en.wikipedia.org/wiki/High_speed_steel
What are the best cobalt drill bits for drilling through hardened steel?
Cobalt drill bits with a high cobalt content (around 5-8) are the best choice for drilling through hardened steel due to their hardness and heat resistance. Look for brands like Irwin, DeWalt, or Bosch for reliable performance.
What mineral has a hardness of 5 Mohs scale nad can be scratched by a steel?
apatite, cobalt, zirconium, palladium, tooth enamel, obsidian (volcanic glass)
What type of drill bit is recommended for drilling into stainless steel?
A cobalt drill bit is recommended for drilling into stainless steel due to its hardness and heat resistance.
Does the chorium cobalt alloy is a very light alloy?
Chromium cobalt alloy is not considered a very light alloy; it is actually a dense material. While it does have high strength, hardness, and corrosion resistance, it is heavier compared to some other alloys like aluminum or titanium.
Can cobalt wedding rings be resized?
Cobalt wedding rings can be resized without damage. The jeweler will heat it to an extreme temperature and make it larger or smaller to fit the finger. Cobalt is popular for rings due to its affordability and durability.
What type of drill bit is best suited for drilling through metal?
For drilling through metal, a cobalt drill bit is best suited due to its hardness and heat resistance.
What type of drill bit is best suited for going through metal?
A cobalt drill bit is best suited for drilling through metal due to its hardness and heat resistance.
What type of drill bit should I use for drilling into stainless steel?
For drilling into stainless steel, it is recommended to use a cobalt drill bit. Cobalt drill bits are specifically designed to handle the hardness of stainless steel and provide better results compared to regular drill bits.
What are the best cobalt drill bits for stainless steel?
The best cobalt drill bits for stainless steel are those with a high cobalt content, typically around 5-8. These bits are specifically designed to withstand the hardness of stainless steel and provide better heat resistance and durability during drilling. Look for brands like Irwin, DeWalt, or Bosch for reliable options.
