Frequently Asked Questions
Q1: What is the difference between HPHT and CVD diamond plates?
HPHT (High Pressure High Temperature) diamonds are grown by mimicking natural conditions, while CVD (Chemical Vapor Deposition) diamonds are grown from a hydrocarbon gas mixture. Both offer Moh's 10 hardness and are suitable for different industrial applications like heat spreaders or cutting tools.
Q2: Can I order customized shapes and sizes?
Yes, customized shapes including round, square, rectangle, and hexagonal configurations are available based on your specific designs and industrial requirements.
Q3: Are these diamonds suitable for optical applications?
Absolutely. Our optical grade diamond plates are ideal for precision tools, optical windows, sensors, and anvils due to their high transparency and low impurity levels.
Q4: How do I choose the right grit size for my tools?
Selection depends on your application. Coarser grits (e.g., 16/18) are for heavy material removal, while micro powders (e.g., 0-0.5) are used for precision polishing and lapping.
Q5: Will these diamonds pass a standard diamond tester?
Yes, since these are chemically and physically identical to natural diamonds with a hardness of 10 on the Mohs scale, they will pass any standard thermal diamond testing pen.
Q6: What is the standard lead time for delivery?
Typically, orders are processed and delivered via air or express transport within 5 to 7 days after the confirmation of your deposit.
