The chart below shows general property
relationships among the various metals used in the manufacturing of
tweezers. In addition, note that the points of the harder metals will
wear longer and are less subject to bending. The softer metals will
not scratch delicate parts and usually have additional desirable
properties such as being non-magnetic, etc. Titanium has a very
high melting temperature and is commonly used when soldering platinum.
