the types of materials used to make these tools,
with different codes by DUMONT-Tweezers.
Carbon steel Carbon steel is an extremely hard alloy (59 HRC) composed of C, Mn and Si. Although carbon provides solid spikes, it will still rust easily. This alloy is magnetic and cannot be sterilized.
Stainless 02 Inox 02 is a standard magnetic stainless steel consisting of C, Mn, Cr and Si. This alloy is not as hard as carbon steels because it contains chromium. Inox 02 withstands temperatures of around 400 degrees Celsius (DIN 50 914), but cannot be sterilized.
Stainless 08 Inox 08 is a medical stainless steel composed of C, Mn, Cr, Mo and V that offers excellent corrosion resistance and good salt resistance. Although not as hard as carbon steels, Inox 08 offers excellent corrosion resistance. This magnetic alloy supports temperatures of about 400 degrees Celsius (DIN 50914) and is suitable for autoclave sterilization at 180 degrees Celsius.
Dumoxel Dumoxel is composed of C, Cr, Ni, Mo and Cu and is the most popular alloy among our customers. This alloy was developed and patented by Dumont to offer the best corrosion resistance thanks to its high concentration of molybdenum and chromium. Dumoxel also guarantees excellent resistance to sulphuric environments, hydrochloric acid and all other mineral and organic acids. Dumoxel is 95% antimagnetic, resistant to temperatures close to 400 degrees Celsius (DIN 50 914) and is suitable for autoclave sterilization at 270 degrees Celsius.
Dumostar This patented Dumont alloy is made up of C, Cr, Mo, Mn, Co, Ni and Si. Dumostar is more elastic and corrosion-resistant than the best stainless steels. It is also perfectly compatible with human tissues and is resistant to mineral and organic acids as well as salt. Although slightly more expensive than other alloys, Dumostar is 100% antimagnetic and withstands sterilization temperatures up to 500 degrees Celsius. It is the most cost-effective and appropriate alloy for laboratory use.
Antimagnetic Antimagnetic is composed of C, Cr, Ni and Mo. It offers good corrosion resistance due to its high concentration of molybdenum and is 80% antimagnetic but is not as hard as Inox. The antimagnetic is resistant to temperatures of about 400 degrees Celsius (DIN 50 914) and is suitable for autoclave sterilization at 270 degrees Celsius.
Titanium Titanium is an alloy composed of C, Fe, O, H, N and Ti. It is totally resistant to corrosion caused by nitric acid, chloride, salt water, etc. This alloy is not as hard as the Inox 08, but it is 40% lighter and more flexible. Titanium 100% antimagnetic and resistant to a temperature of about 430 degrees C.
nickel Nickel is a 100% antimagnetic alloy composed of Cu, Ni, Mn and Zn. It is widely appreciated because it does not damage the components it handles.
Black ceramics ZrO2 ceramics are even harder than stainless steel and contain no carbon or other metal additives. It offers good resistance to chemicals and is safe for electrostatic discharges. Black Ceramic is compatible with antimagnetic (residual zero magnetism) and microwave sterilization. It does not produce metal contamination and provides good thermal insulation for welding. welding does not adhere to its surface. Black ceramics are safe for the clean room and are available in antistatic version for CMOS.
White Ceramics ZrO2 ceramics are even harder than stainless steel and contain no carbon or other metal additives. It offers good resistance to chemicals and is safe for electrostatic discharges. White ceramics are compatible with antimagnetic (zero residual magnetism) and microwave sterilization. It does not produce metal contamination and provides good thermal insulation for welding. welding does not adhere to its surface. White ceramics are safe for clean rooms and are available in antistatic versions for CMOS.
Brass or Brass Brass is composed of Cu, Pb, Sn, Ni and Zn. This alloy is 100% antimagnetic and is widely used for handling delicate components, especially in watchmaking.
