The high quality
micro-dissecting tweezers on the following pages are available in a
number of different steel alloys. Which alloy to choose is very
important and depends on how you intend to use the tweezer. The
information below is provided to help compare the various alloys and
their respective properties. Please note that not all tweezer patterns
are available in all alloys.
CARBON STEEL: At
Rockwell 60, carbon steel is one of the hardest tweezer steels. Carbon
steel tips are very durable but because of this hardness, carbon steel
tips are more brittle than some of the other steels. Carbon steel is
also highly magnetic and stains easily.
TITANIUM: While
not as hard as some of the other alloys (Rockwell 37 at tips),
titanium tips are very flexible. Another unique property of titanium
is that it is 33% lighter than other stainless alloys. Titanium is
extremely corrosion and stain resistant, making it the preferred
choice for salt water uses. Titanium also has a high heat resistance
in excess of 400oC and is completely non-magnetic.
STAINLESS STEEL: The
common name for various alloys composed of carbon steel and chromium.
Alloys considered stainless exhibit good stain resistance and have
varying degrees magnetism.
INOX: Inox
is a specific stainless alloy composed of carbon steel and chromium.
Inox tips are more flexible than pure carbon steel but not as hard
(Rockwell 55). Inox has good stain resistance and is magnetic.
DUMOXEL: One
of the most popular tweezer alloys, Dumoxel is even more stain
resistant than Inox and is highly corrosion resistant. With a Rockwell
36 at the tips, tweezers made from this alloy have very soft, flexible
tips. Dumoxel is non-magnetic and exhibits high temperature
resistance.
DUMOSTAR: This
new alloy is a blend of steel, chromium, nickel, cobalt and has many
of the best features of the other alloys. Dumostar is heat resistant
to over 500oC and is completely non-magnetic. Dumostar is extremely
corrosion resistant and is one of the harder alloys at Rockwell 62.
However, because of its unique composition, Dumostar tips are very
flexible, are resistant to fatigue, and are capable of flexing far
beyond other alloys without permanently deforming. This alloy is far
superior in overall performance than any other material available
today!
