Gasket Blanks

We can offer a wide range of gasket blanks for your diamond anvil cells and for your experiment. Note that all our diamond anvil cells comes supplied with 20 blank gaskets as standard but you might need to replenish your stock or you might want for specific experimental requirements to change gasket materials.

Material:

  • BeCu: usually selected for low temperature application where a low magnetic background and surrounding is required for the measurements. BeCu gaskets can be used in a non-hardened state (making it softer than stainless steel) or hardened. In the hardened state BeCu can sometime become brittle under constraint;
  • Hastelloy® Hybrid BC1® : presents a viable alternative as a gasket material for low-temperature magnetic measurements. This alloy strikes a balance in hardness, being softer than hardened MP35N yet harder than hardened BeCu. A key benefit of using Hastelloy® Hybrid BC1® is its lower magnetic background compared to MP35N;
  • Stainless Steel: for low to moderate pressure (typically 20-30 GPa max). Stainless steel is a relatively soft material making it easy to work with for such pressure;
  • Inconel: Usually good for moderate pressure and also for high temperature applications;
  • MP35N: is a newcomer in the choice of gasket material. Based on the known MP35N (Timken Latrobe) super alloy, the MP35N offers a very good compromise strength – relatively low magnetic background;
  • Rhenium (Re): the premium choice for gasket material and particularly suited for work at higher pressure. Offering a very good support for the diamond anvils, it is a material used for pressure above 50 GPa. The price of these gaskets also reflects its premium properties.
Material Ultimate Tensile Strength (MPa)
BeCu (1/2H) 580-690
BeCu (Heat T) 1190
Hybrid BC-1 (Hardened) 1216
Stainless Steel 1460
Inconel 1240-1380
MP35N (Hardened) 1790-2070
Rhenium 2500

Diameter & thickness:

  • Diameter will be depending on your pressure cell. If you are using a DAC from Almax easyLab, the choice will be 5mm or 10mm in diameter (more rarely 3 or 3.5mm).
  • Thickness will be depending on the material. Thicker gaskets tend to be the natural choice for low pressure work where larger sample space is sought after.
