I. Manufacturing Technique

Various pore size sintered porous material is made of metal or alloy powder by forming and sintering at high temperature and with a rigid structure.

Production Steps: Filtrate-- Isostatic compaction--Vacuum sintering

Feature: the material contains a large number of connected or semi-connected pores, the pore structure is composed of regular and irregular powder particles, the size and distribution of pores and the size of porosity can be adjusted according to the powder particle size combination and preparation process to meet the actual needs of customers.

Advantage: good permeability, pore size, and porosity are controllable, shape stability, high filtration accuracy, wear-proof, good mechanical properties, good thermal conductivity, heat resistance, heat dissipation performance, backflush, and reuse.

II. Properties of various pore size sintered porous titanium materials:

• High-temperature resistance, in normal use 300 ℃.
