Product Description

High density tungsten alloys are used in the drilling industry:

High density tungsten alloy used as drill bit tools and counterweight materials in professional drilling engineering
The drilling of oil, natural gas, and groundwater involves using mechanical equipment to drill the formation into cylindrical holes with a certain depth. A cylindrical circular hole with a smaller diameter and a larger depth drilled underground using drilling equipment. The main function is: A) to obtain underground physical data, that is, to take rock cores, ore cores, rock cuttings, liquid samples, gas samples, etc. from drilling. B) As a geophysical logging channel, obtain data on various geophysical fields of rock and mineral layers. C) As an artificial channel for observing the hydrogeological dynamics of groundwater layers. D) Used for drilling in combination with exploration and production to develop groundwater, oil and gas, geothermal energy, etc.
High density tungsten alloy has high hardness, density, strength, impact resistance, and stable mechanical properties. Therefore, it is the best material for manufacturing drilling equipment. With high density and great weight, it can easily enter the barite mud, and high hardness, it can withstand water pressure in harsh environments such as ultra-low temperatures. The design of drilling equipment requires highly processed detectors to provide positioning. The stability of mechanical performance plays a crucial role in the operation of these components. High density tungsten alloy has a maximum density of 18.75g/cm3 and a hardness of 35HRC, making it the preferred material for drill bits in drilling engineering.
