Porous Alumina /Aluminium Oxident /AlO Ceramic Foam Filters for Aluminium Alloys Casting
With its internal interconnected three-dimensional structure, the foam ceramic filter can fully embody its four major filtration mechanisms of rectification, mechanical screening, "filter cake" and adsorption when filtering molten metal. At the same time, the filter material has good chemical stability , does not react with the alloy liquid, thereby effectively removing or reducing inclusions in the metal liquid such as copper parts and iron parts, thereby improving the purity of the metal melt, making the surface of the poured metal castings smooth, improving the strength, and reducing the scrap rate,Reduce machining losses.
The alumina foam ceramic filter can effectively remove large inclusions and adsorb tiny inclusion particles in the aluminum liquid, improve the surface quality of castings, improve product performance and improve the microstructure, and can effectively improve the casting yield. It is widely used in production fields such as aluminum alloy castings.

Pores (ppi): 10 15 20 25 30
Thinkness (mm): 10-50>> Placement location: ALO alumina foam ceramic filter can be placed in various parts of the casting system. The closer to the inner gate, the better the filtration and purification.
>> Filtration area: Due to the blocking effect of the filter and the gradual blockage of some mesh holes, the cross-sectional area of the filter is required to be larger than the normal sprue cross-section, generally 2-3 times the normal sprue cross-section.
Q1: What information should I let you know if i want to get a quotation?
A: The required material dimension (Thickness*Width*Length,diameter*length; if possible, please kindly supply us drawings).
The required more information, such as Surface Condition, Tolerance Request, The Quantity, and other mechanical and technical details.
If it is possible, please also provide the application of products, we will recommend the most suitable products with details for confirmation.
Q2: How do you gurantee the quality of the products?
A: Each step of production and finished products will be carried out inspection by QC department before storing in the warehouse. NG goods are not allowed in the completed goods warehouse.
Q3: Can you guarantee the prompt delivery?
A: Yes, when we get your inquiries, not only we will evaluate the more competitive price, but also we can get the most reasonable delivery time. So the prompt delivery can be guaranteed.
Q4: What is your lead time?
A : It usually needs about 15- 20 days after receiving the PO.
Q5 : What is your payments terms?
A : T/T, Western Union, etc., could be acceptable.
Q6 : Can we visit your company?
A : Yes, for sure, It's my pleasure to visit our company.
Q7 : What is the shipping cost?
A: The shipping cost is determined by the destination port, weight, packing size, total CBM of the products, we will try best to get the most reasonable shipping cost from the forwarders or express couriers to help you save more money.
Q8 :What is the transportation way?
A:If the Gross Weight ≤45kg, it's better by express such as TNT, DHL, FedEx,, etc.
If the Gross Weight between 45kg to 100kg, by express or by air to your nearest airport can be both considered.
If the Gross Weight ≥ 100kg ,you can choose by Air or Sea to the nearest port.
Q9 :How service you can offer your clients?
A:We provide presales service in various forms, for example, making investment budget,manufacturing planning,etc.so that customer make a reasonable plan with less cost. Moreover,we will also provide after sale service ,for example,free training about machine applications ect.
