Our Advantage:
1. For Samples: We can provide samples free for your testing.
2. Quality: Firstly, We control the quality of raw materials(alumina powder) strictly
Second, After the block of WFA crushed into piece,
we will do chemical analysis of lump from every furnace in Lab.
Thirdly, We will choose the finished goods from diffrent directions of bag and
mixed them to do the lab test in many times, so that the goods are qualify.
3. Delivery Time: Whithin 15~20 working days after reciept of the deposit or L/C at sight.
