Castrol Hysol MB 20 is a versatile, low maintenance semi-synthetic metalworking fluid for machining and grinding ferrous and aluminum alloys. It is low foaming in all water conditions, with excellent wetting properties to reduce fluid drag-out and keep tools land components clean. MB 20 provides excellent bio resistance without a bactericide or fungicide, and is an excellent choice for industrial sumps and central systems.

Castrol Hysol MB 50 is a high performance, soluble metalworking fluid for all grades of aluminum and ferrous alloys. It was engineered specifically for automotive and aerospace aluminum. MB 50 delivers the performance of heavy duty soluble oils without the unpleasant shop environment or high usage rate of traditional fluids. It is chlorine, sulfur and formaldehyde-free, and exceeds the performance of products containing these extreme pressure additives. The light, stable emulsion of MB 50 maximizes system life while inhibiting microbial growth.

Alusol AU 68 soluble semi-synthetic metalworking fluid was engineered for heavy duty manufacturing of aerospace alloys and automotive aluminum. Designed to meet stringent HSSE requirements, it is chlorine, boron, phosphorous and sulfur-free, with performance that exceeds soluble oils that contain these extreme pressure additives. The light, stable emulsion provides excellent tramp oil rejection, and is compatible with all water conditions.

Alusol AU 70 semi-synthetic metalworking fluid was engineered for heavy duty manufacturing applications. It is multi-purpose, multi-metal compatible, and free of boron, chlorine, phosphorous and sulfur. Its additive package enhances machining performance and surface finish, adds stability, enhances bio resistance and lowers total operations costs. It is ideal for large central systems and single sump machines.
