Master Alloys
Al-Ti-B grain refiner, Al-Sr modifier and Al-Mn, Al-Fe hardeners
Overview
What it is and where it works
Aluminium-based master alloys for adjusting melt chemistry and structure: Al-Ti-B grain refiner, Al-Sr eutectic modifier for Al-Si alloys, and Al-Mn and Al-Fe hardeners for composition correction. Supplied as rod, waffle or ingot. We source to your composition spec and ask for a certificate of analysis per lot.
- AlTi5B1
- Ti 4.5 to 5.5 %, B 0.9 to 1.5 %, balance Al; supplied as waffle or rod
- Grain refining
- TiB2 and Al3Ti particles act as nucleation sites for aluminium grains
- Al-10Sr
- Used to modify eutectic silicon in Al-Si alloys; one study on 319 alloy added 8 to 96 ppm Sr
In your plant
Where It Is Used
- Grain refining of casting and wrought alloys
- Eutectic Si modification in A356, 319 and similar Al-Si alloys
- Mn and Fe correction in secondary alloys

Frequently Asked Questions
Can I add grain refiner and Sr modifier together?
It is done, but boron can interact with strontium and weaken modification. Addition order and levels should be set for your alloy.
Do you supply a certificate per lot?
Yes, we request a certificate of analysis for each lot and check it against your spec.
