Specification of Quality White High Durable High Purity Alumina Ceramic Foam Filter

Here’s the product description for the alumina ceramic foam filter:

This quality white alumina ceramic foam filter cleans molten metal effectively. It removes impurities like oxides and slag from aluminum, copper, and other non-ferrous alloys. High purity alumina material ensures excellent chemical resistance. It withstands the harsh environment inside furnaces and casting units. This filter handles temperatures up to 1700°C easily. Its key strength is exceptional durability. The rigid foam structure resists thermal shock and mechanical stress during pouring. This prevents cracking and guarantees reliable performance filter after filter. You get consistent flow rates and cleaner castings. The uniform, open-cell foam structure provides precise filtration control. Standard pore sizes include 10, 20, 30, and 40 pores per inch (PPI). Choose the right PPI based on your alloy and required metal cleanliness level. The fine white surface clearly shows trapped inclusions after use. This helps monitor your melt quality. Expect low metal loss during filtration. The filter captures impurities efficiently without absorbing excessive metal. Its high strength reduces breakage risks during handling and installation. This filter integrates smoothly into existing launder systems. It fits standard filter boxes and holders. Using this filter improves final product quality significantly. You achieve fewer defects like porosity and inclusions in your cast parts. This leads to better mechanical properties and surface finish. It is a dependable solution for foundries demanding high purity metal.

Applications of Quality White High Durable High Purity Alumina Ceramic Foam Filter

Metal casting often suffers from contamination. Tiny bits of junk get stuck in the liquid metal. This junk causes problems later. Porosity appears. Weak spots form. The final metal part fails. Alumina ceramic foam filters solve this. They act like a super fine sieve. Liquid metal flows through their open pores. Solid impurities get trapped inside the foam structure.

The aluminum industry relies heavily on these filters. They are placed in the metal flow path. Before the metal enters the mold. The filter catches oxides, slag, and other debris. Cleaner aluminum fills the mold. The result is better castings. Fewer defects happen. Less scrap metal is produced. This saves money. It improves production efficiency.

Steel foundries also use these filters. High-purity alumina handles extreme heat. Molten steel doesn’t damage the filter. The filter removes inclusions effectively. Cleaner steel means higher quality final products. Superalloy producers need this too. Impurities ruin these expensive metals. The filter ensures purity is maintained.

The material itself is key. High-purity alumina ceramic is very strong. It resists thermal shock extremely well. Sudden temperature changes don’t crack it. The white color helps spot trapped dirt. The open-cell foam structure offers high flow rates. Metal passes through without slowing down much. Operators see the benefit immediately. Cleaner metal means better castings every time.

5 FAQs of Quality White High Durable High Purity Alumina Ceramic Foam Filter

Here are 5 common questions about our Quality White High Durable High Purity Alumina Ceramic Foam Filter:

What is this filter made of?
This filter uses high purity alumina. The purity level is over 99%. This material choice ensures excellent performance. It handles molten metal well.

Why does it last so long?
The alumina material is very strong. It resists heat extremely well. It doesn’t crack easily under thermal stress. This strength means the filter lasts longer in tough conditions. You get more casts per filter.

What pore sizes do you offer?
We provide different pore sizes. Common options are 10 PPI, 20 PPI, 30 PPI. PPI means pores per inch. Smaller pores catch finer impurities. Choose the size based on your metal type and purity needs. Tell us your application.

How hot can it get?
This filter handles extreme temperatures. It works reliably up to 1700°C (3092°F). This covers most aluminum and other non-ferrous metal casting temperatures. It stays stable. It won’t melt or degrade.

How should I handle it?
Handle the filter carefully before use. It is strong under heat but brittle at room temperature. Avoid dropping it or hitting it hard. Store it in a dry place. Keep it in its packaging until you need it. Moisture is bad for unfired ceramics.
