Aluminum nitride ceramic industrial parts / Aluminum nitride heater
Application
High Temperature and Aggressive Environments
Its high free energy of formation makes alumina chemically stable and refractory, and hence it finds uses in containment of aggressive and high temperature environments.
Wear and Corrosion Resistance
The high hardness of alumina imparts wear and abrasion resistance and hence it is used in diverse applications such as wear resistant linings for pipes and vessels, pump and faucet seals, thread and wire guides etc.
Biomedical
High purity aluminas are also used as orthopaedic implants particularly in hip replacement surgery.
Product Description
Aluminium Nitride (AlN) is an ideal choice for heat dissipation substrate in electrical applications. It has high mechanical hardness, high thermal conductivity, similar thermal expansion coefficient with Si, excellent electrical resistivity and good chemical stability. Besides, Aluminium Nitride is non-toxic.
Surface oxidization will happan when operating temperature is in excess of the maximum. In oxidizing atmospheres, this happens around 700℃. In inert atmospheres this happens around 1300℃.
Due to different forming methods, there are three types of aln ceramic in our company, Tap Casting AlN, Dry Pressed AlNand Hot Pressed AlN, tap casting is suitable for thin ceramic sheet of thickness<2mm, dry pressed and hot pressed is suitable for thick ceramic sheet and other shaped parts.
Typical properties of Aluminum Nitride:
1.Very high thermal conductivity
2.Excellent electrical insulation(Low dielectric constant and loss)
3.Low density
4.Similar linear expansion coefficient with Si
5.Extremely high hardness
FAQ
Q: Is it possible to provide samples?
A: We can supply 1-2 samples, but we do not bear the shipping cost of the samples.
Q: How long is the delivery time usually?
A: Product delivery is subject to order quantity and processing requirements, and different product delivery times are inconsistent. Generally speaking, the delivery time of 1-2 common product samples is about 35 days.
Q: Which payment methods are supported?
A: T/T; credit card. Currently our company supports these two payment methods.
Q: What is the shipping date? How long can I ship?
A1: Shipped within 72 hours after the balance is settled
A2: After the production of the product is completed and passed the internal inspection of the company, we will send the finished product image to the customer for confirmation. After the balance is settled, all the products will be sent to the customer's designated delivery location.
