• Aluminum Oxide / Aluminate Type: Alumina / Aluminum Oxide
• Shape / Form: Tube Stock

Description: San Jose Delta maintains an in-house inventory of most grades of alumina ceramics as BARS-RODS-TUBES and SHEETS. The availability of fired “grinding stock” ceramic makes the production of small quantity and prototype orders less costly and offers shorter lead-times. For larger

• Aluminum Oxide / Aluminate Type: Alumina / Aluminum Oxide
• Applications: Wear Parts / Tooling, Abrasive / Erosive Wear Protection, Dielectric Ceramics / Materials, Refractory / High Temperature Materials, Electrical / HV Parts, Electronics / RF-Microwave
• Coeff. of Thermal Expansion (CTE): 7.9 µm/m-C
• Compressive / Crushing Strength: 323000 psi

Description: Sharp edges at the ends may be broken to prevent chipping. Thread may be countersunk a maximum of 1/16" deep to prevent chipping. .006"/ inch max camber allowance. Threads must accept a Class 1 metal screw to the above minimum thread depth. Threads will be perpendicular

• Aluminum Oxide / Aluminate Type: Alumina / Aluminum Oxide
• Applications: Dielectric Ceramics / Materials, Electrical / HV Parts, Electronics / RF-Microwave
• Length: 4 inch
• Shape / Form: Ferrule / Eyelet, Rod Stock

Description: helix support rods, termination wedges, heatsinks, etc.,we apply the same basic manufacturing processes to produce these designs using aluminum nitride. AlN is somewhat more challenging than some other technical ceramic because the fine grained grinding powder adheres to the diamond tooling

• Applications: Wear Parts / Tooling, Dielectric Ceramics / Materials
• Coeff. of Thermal Expansion (CTE): 5 µm/m-C
• Density: 3.27 g/cc
• Dielectric Constant (Relative Permittivity): 9 #

Description: Bolt lengths do not include head lengths. Threads are manufactured to "go" gauge conditions. Parts will not meet "no-go" gauge conditions. Due to standard manufacturing methods, stack-up tolerances cannot be controlled on the pitch. It is therefore recommended that the thread depth
