FAQ – Frequently Asked Questions about Castrol ALUSOL SL 61 XBB
Is ALUSOL SL 61 XBB designed specifically for aluminium alloys?
Yes. The formulation is tailored for aluminium-focused machining, preventing staining, corrosion effects, and surface discolouration on sensitive alloys.
Can it be used for mixed-metal machining environments?
Yes, it also supports steel, cast iron and selected non-ferrous materials without compromising surface finish or stability.
How stable is the coolant in long-term operation?
The XBB technology ensures excellent pH and biological stability, even in extended service intervals.
Does it help reduce total manufacturing cost per part?
Yes, through extended tool life, reduced maintenance interventions and low additive consumption.
Is it compatible with central coolant systems?
Yes. It works reliably in individual sumps and large-scale centralized systems.
