Abstract
A clamping tool having a clamping head, a cylinder member coupled to an edge portion of the clamping head, a ram member coupled to and movably arranged within the cylinder member, a first die member coupled to the clamping head, and a second die member arranged to face the first die member and movable by the ram member toward and away from the first die member, wherein at least the clamping head is formed of a composite material prepared by dispersing at least one reinforcing material selected from the group consisting of ceramic fibers, ceramic whiskers and ceramic particles into a matrix metal consisting essentially of an aluminum alloy or a magnesium alloy. The clamping head is light, has a high Young's modulus, exhibits a high fatigue resistance, and is free from cracking and scattering of the cracked pieces. The clamping tool permits an operator to operate the clamping tool under a safe environment, and lessens the burden given to the operator, leading to an improved working efficiency.
