Abstract
A material for porous metal body having a coil shape of a wire material wound in a helical shape, made of metal which having good thermal conductivity and can join by sintering; an average wire diameter Dw of the wire material is 0.05 mm to 2.00 mm inclusive, an average coil outer diameter Dc is 0.5 mm to 10.0 mm inclusive, a coil length L of 1 mm to 20 mm inclusive, and a winding number N is 1 to 10; and the plurality of materials for porous metal body are combined and sintered to form a metal porous body having a plurality of pores so that a pore ratio of the metal porous body is facilitated to be controlled.
Claims11
A material for metal porous body for composing a metal porous body having a plurality of pores, which is a wire material having a coil shape wound in a helical shape, wherein
- the wire material has an average wire diameter Dw of not less than 0.05 mm and not more than 2.00 mm;
- the coil shape has an average coil outer diameter Dc of not less than 0.5 mm and not more than 10.0 mm, a coil length L of not less than 1 mm and not more than 20 mm, and a coil winding number N of not less than 1 and not more than 10;
- wherein the material for metal porous body in a state in which one end thereof along a direction following the coil length L is supported in a cantilever manner and the other end is deflected with a deflection amount δ by its own weight,
- a deflection ratio (δ/L) of the coil length L and the deflection amount δ is not more than 0.20.
