High Precision Ruby Balls

Ruby Balls

Synthetic ruby, known for its exceptional hardness second only to diamonds, exhibits excellent high-temperature resistance and is resistant to damage or deformation in high-temperature environments. It also demonstrates strong corrosion resistance to acids, alkalis, and other chemical substances. The material has a density of 3.9 – 4.0 g/cm³, a hardness of 9 on the Mohs scale, a melting point of 2050°C, and excellent wear resistance.

GELINDE’s ruby balls find extensive applications in precision mechanical bearings, measurement instrument probes, pumps, valves, as well as high-temperature testing and heating equipment.

FAQ About Ruby Ball

Based on the raw material of monocrystalline aluminum, ruby balls can apply on the precision bearings, measurement probes, pumps, valves, and high-temperature equipment.

This material is not just any ordinary ceramic; it’s a ceramic that has been refined, redefined, and perfected to meet the highest standards of quality and precision. One of the first things you’ll notice about a ruby ball is its captivating visual appeal. The monocrystalline structure gives it a translucent, jewel-like appearance reminiscent of the finest rubies used in luxury jewelry. This visual allure isn’t just for aesthetics; it’s a testament to the material’s purity and consistency.

The ruby gemstone contains traces of chromium. They contain a trace of chromium to produce its red color, making it easier to identify and making it visually appealing. As a form of monocrystalline aluminum oxide-based ceramics, ruby balls boast impressive durability and resistance to wear. They are also transparent, making them an excellent choice for optical applications, especially when clarity is crucial. Sapphire balls, like their ruby counterparts, are made from monocrystalline aluminum oxide, offering similar durability and resistance. Sapphire balls are however clear and colorless, making them ideal for applications where color interference might be an issue. Measuring nine on the Mohs scale, sapphire balls are incredibly hard, ensuring longevity in high-wear applications. Finally, cubic zirconia balls offer a balance of quality and value. With a rating of 8 – 8.5 on the Mohs scale, they’re hard and durable. A high refractive index makes cubic zirconia ideal for optical applications, especially in lenses. However, still durable, cubic zirconia may not offer the same wear resistance as ruby or sapphire.
