Alloys and Materials
DS DUMOSTAR
An alloy blend of steel, chromium, nickel, and cobalt, elastic in nature for “flexible fatigue resistant tips”, resists temperatures to 550°C, and is non-magnetic and anti-corrosive. The best overall material for tweezers. Rockwell 63-64.
SS Stainless Steel
High tensile strength chromium/carbon steel alloy (various compositions) provides for good corrosion and stain resistance, second in hardness only to DUMOSTAR Note: stainless steel can rust under some circumstances.
NM-SS Non-magnetic Stainless Steel
Same properties of stainless steel with additional nickel to create the non-magnetic characteristic.
NM Non-magnetic
A standard alloy composed of C, Cr, Ni and Mo. It offers a good resistance to corrosion thanks to its high concentration of Mo and is 80% non-magnetic, but it is not as hard as NM-stainless steel. NM is resistant up to temperatures of around 400°C (DIN 50 914) and is suitable for autoclave sterilization at 270°C.
Ti Titanium
Flexible tips, non-magnetic, light weight (33% less than stainless steel alloys), durable, low particle shedding compared to stainless steel, extremely acid and stain resistant, hypoallergenic. Good for use around sensitive electronics or high magnetic fields. Will resist temperatures in excess of 400°C. Rockwell 36.
CS Carbon Steel
Very durable, hard material that is less flexible and more brittle than DS, SS and Ti. Highly magnetic, will stain and rust easily. Rockwell 60.
DUMOXEL SS Stainless Steel Alloy
Highly corrosive resistant and provides soft, flexible tips. More stain resistant than stainless steel, Rockwell 36 hardness. 95% anti-magnetic, resistant to temperatures above 400°C. Can be autoclaved.
INOX SS Stainless Steel Alloy
Composed of a special mix of Carbon Steel and Chromium. Provides soft, flexible tips, Rockwell 55.
