Materials for porous sintered components
The choice of material is a key factor in the performance, durability, and compatibility of porous sintered components. At PORAL, we manufacture our products using high-quality stainless steel, bronze, and selected alloys.
Porous sintered
component materials.
Each material offers specific advantages to meet the technical and environmental requirements of various industrial applications. Explore our materials to find the best fit for your needs.
Stainless steel components
Common usage for food application. Often used in oxidizing conditions with nitric or organic acids (except formic and oxalic) with sulphuric phosphoric of hydrochloric acids, heat resistants.
Bronze components
Good corrosion resistance in sea water. Compatible with oxygen, hot/cold frashwater or with diluted non-oxidizing acids (without air). Typically used for hydraulic and pneumatic applications.
Inconel components
Good resistance to corrosion and heat. Good resistance to oxidizing conditions at high temperature. Resists to oxidizing in corrosive solutions and to sulfur compounds.
Typically used in nuclear, chemical and heat treating industry for its strenght and corrosion resistance.
Monel 400 components
Resist to anhydrous hydrofluoric acid to chlorine derivatives, fluorine, HeS04; NaOH
Hastelloy X components
High resistance under high temperatures oxidizing atmosphere.
Hastelloy c276 components
Good resistance to HF, HN03.

Material selection &
filtration efficiency.
The efficiency values below are given for air and water at a given flow rate.
Stainless steel
filtration efficiency.
Stainless steel is known for its excellent filtration efficiency, particularly due to its controlled porous structure when sintered. Resistant to corrosion, high temperatures, and chemicals, it is ideal for filtering liquids or gases in demanding environments. Its smooth surface reduces particle buildup and makes cleaning easier, allowing for frequent reuse without performance loss. Thus, stainless steel offers a durable, reliable, and high-performance filtration solution in various industries, including food processing, pharmaceuticals, and petrochemicals
Bronze
filtration efficiency.
Bronze, often used in sintered form, provides good filtration efficiency thanks to its uniform porous structure. It is particularly suited for filtering liquids and gases in industrial applications, due to its resistance to wear and corrosion. Less expensive than some noble metals, it offers a solid balance between performance and durability. Filter-grade bronze is also valued for its ability to withstand repeated cleaning while maintaining its filtering properties.
