30ppi Asian Foundry Filters are the most commonly used ceramic foam filter in the aluminum casting industry.
Most factories use 30ppi and 40ppi CFF to filter the aluminum slag after the degassing process in the process of processing molten aluminum.
Ordinary aluminum casting usually uses 10-40ppi ceramic filter plates.
Aviation and high-quality aluminum materials usually use 30-60ppi ceramic filter plates.

30ppi Asian Foundry Filters

Ceramic foam filter Dimension

Ceramic foam filter Pore Size (PPI): 10/20/30/40/50/60

Ceramic Foam Filter is a kind of effective molten metal filter.
It’s three-dimensional connected mesh structure and high porosity has many advantages, for example, large surface area of ​​slags collection. Large inner surface area of ​​filtering.
small flow resistance.good filtering effect.etc. SIC Ceramic Foam Filter is one of the size ,the size can be customized.

Inclusions and gases in the metal have a significant impact on the strength, fatigue resistance, corrosion resistance, and stress corrosion cracking performance of the material.
30ppi Asian Foundry Filters effectively control the oxidized inclusions in the melt to improve the quality of the cast rod is the common goal pursued by the aluminum industry.

Part of the inclusions in aluminum alloy come directly from scrap, and most of them are formed during the melting and pouring process, mainly oxide inclusions.

Automobile and motorcycle wheels, steering knuckles, cylinder pistons, cylinder heads, aluminum ingots, aluminum materials and other precision cast aluminum alloy parts in aluminum alloy casting. The molten aluminum contains certain slag during casting, and the molten aluminum contacts air. It is easy to be oxidized and produce impurities such as oxide scale.
