Product Description Product DescriptionGraphite heater serves as an electric heating component crafted from graphite materials. Graphite, renowned for its excellent electrical and thermal conductivity, finds widespread application as a heating element in specialized industrial furnaces. Despite having lower strength than metals at room temperature, graphite exhibits remarkable high-temperature strength. As temperatures rise, the strength of graphite progressively increases, surpassing that of all oxides and metals.Graphite possesses a unique combination of metallic and ceramic properties. It boasts exceptional electrical and thermal conductivity, a compact structure, and a minimal thermal expansion coefficient. These characteristics make graphite stand out as one of the top materials for superior thermal shock resistance, solidifying its position as a crucial component in the realm of high-temperature applications.

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.
