THE VARIOUS MATERIALS USED IN THE MANFACTURING OF DUMONT INSTRUMENTS

Matériaux Dumont

Le carbone (01)

Carbon steel (01) is an extremely hard alloy (> 59HRC) composed of C, Mn and Si. While carbon ensures strong tips, it can nevertheless easily rust. This alloy is magnetic and cannot be sterilized.

Inox (02)

Inox 02 is composed of C, Mn, Cr and Si and is standard magnetic stainless steel. This alloy is not as hard as carbon steels because it contains chromium. Inox (02) will resist temperatures of around 400°C (DIN 50 914) but cannot be sterilized.

Inox (08)

Inox (08) is a medical stainless steel composed of C, Mn, Cr, Mo, and V that provides excellent resistance to corrosion and good resistance to salt. Although not as hard as carbon steels, Inox (08) offers superior resistance to corrosion. This magnetic alloy withstands temperatures of around 400°C (DIN 50 914) and is suitable for autoclave sterilization at 180°C.

Dumoxel ® (03)

Dumoxel alloy is composed of C, Cr, Ni, Mo and Cu and is the most popular steel among our customers. This alloy was developed and patented by Dumont to offer the best in resistance to corrosion thanks to its high concentration of molybdenum and chromium. Dumoxel also guarantees an excellent resistance to sulphuric environments, hydrochloric acid, as well as to all other mineral and organic acids. Dumoxel is 95% antimagnetic, resistant up to temperatures of around 400°C (DIN 50 914) and is suitable for autoclave sterilization at 270°C.

Dumostar® (09)*

This Dumont patented alloy is composed of C, Cr, Mo, Mn, Co, Ni and Si. Dumostar is more elastic and more resistant to corrosion than the best stainless steels. It is also perfectly compatible with human tissue and is resistant to mineral and organic acids as well to salt. Although slightly more expensive than other alloys, Dumostar is 100% antimagnetic and is resistant to sterilization temperatures of up to 500°C. This is the most cost-effective and appropriate alloy for laboratory use.

Brass (06)

Brass is composed of Cu, Pb, Sn, Ni and Zn. This alloy is 100% antimagnetic and is widely used in handling delicate components, particularly in watch-making.

White ceramic tips

Ceramic ZrO2 is even harder than stainless steel and does not contain carbon or other metal additives. It offers good resistance to chemicals and is electrostatic discharge safe. White ceramic tips are antimagnetic (zero residual magnetism) and microwave-sterilization compatible. They do not produce metallic contamination and offer good thermal isolation for soldering; solder will not adhere to their surfaces. White ceramic tips are clean room safe and are available in anti-static versions for CMOS.

Black ceramic tips

Ceramic ZrO2 is even harder than stainless steel and does not contain carbon or other metal additives. It offers good resistance to chemicals and is electrostatic discharge safe. Black ceramic tips are antimagnetic (zero residual magnetism) and microwave-sterilization compatible. They do not produce metallic contamination and offer good thermal isolation for soldering; solder will not adhere to their surfaces. Black ceramic tips are clean room safe and are available in anti-static versions for CMOS.

Nickel (05)

Nickel is a 100% antimagnetic alloy composed of Cu, Ni, Mn and Zn. It is widely appreciated as an alloy as it does not damage the components handled by it.

Titanium (07)

Titanium is an alloy composed of C, Fe, O, H, N and Ti. It is totally resistant to corrosion from nitric acid, chloride, salt water and the like. This alloy is not as hard as Inox 08 but is 40% lighter and offers greater flexibility. Titanium is 100% antimagnetic and resistant up to temperatures of around 430°C.

Antimagnetic (04)

Antimagnetic alloy is a standard alloy composed of C, Cr, Ni and Mo. It offers good resistance to corrosion thanks to its high concentration of molybdenum and is 80% antimagnetic, but is not as hard as Inox. Antimagnetic is resistant up to temperatures of around 400°C (DIN 50 914) and is suitable for autoclave sterilization at 270°C.
