FAQs

1. What are the typical compositions of tin‑ and lead‑based Babbitt alloys?

Tin-based Babbitts generally contain 80–90% tin, 5–15% antimony, and 1–6% copper, while lead-based ones include 70–80% lead, 5–15% antimony, and minor copper or tin .

2. How do tin-based and lead-based Babbitts compare in performance?

Tin-based alloys offer higher load capacity and speed resistance, plus they tolerate higher temperatures—ideal for demanding applications. Lead-based alloys are softer, more corrosion-resistant, and more cost-effective for moderate loads .

3. Which alloy type suits marine and turbine bearings?

RA Power Solutions supplies both tin- and lead-based Babbitt alloys tailored to client specs. Tin-based versions are preferred for turbines and high-speed machinery, while lead-based are ideal for marine and high-humidity environments .

4. What global reach does RA Power Solutions have in Babbitt alloy supply?

With over 45 years of experience, RA Power exports Babbitt alloys worldwide—serving regions from Europe and Latin America to the Middle East and Africa.

5. Do you provide composition reports and quality assurance?

Yes—every Babbitt ingot is custom-mixed per international standards or client specs, and accompanied by metallurgical lab reports.
