Product Description
High Purity Alumina Cake
The high purity alumina cakes we produced are mainly used as raw materials for sapphire crystal nucleation, featuring high purity, high density, etc. Currently we can provide high purity alumina cakes with 99.996-99.999% purity and 3.5-3.7g/cm3 density.
The product’s detailed specifications are as below:
| Crystalline phase | appearance | Purity% | Specifications | Impurity content(ppm) | |||||||||

Note: Dimensions and shapes are adjustable as per clients’ requirements.
We mainly produce 5N, 5N5-6N5 ultra pure aluminum and aluminum alloy materials, and what’s worth noting is that we are the first in China to successfully develop and produce 6N5 ultra pure aluminum. We are capable of producing 1,200 tons of high purity aluminum annually and can provide round ingots, slab ingots, sections of high purity aluminum of various dimensions such as 30-Φ450mm and 1070×380mm, as well as cast ingots, targets and sections of aluminum alloys as per our clients’ requirements.
