ER4047 is commonly known for its low melting point and narrow freezing range. It has an increased silicon content compared to ER4043 which allows for reduced shrinkage in the weld due to a higher level of fluidity. ER4047 offers a bright and clean weld. This alloy may be able to be used in high-temperature situations as its additional silicon content reduces hot cracking and increases the welds shear strength. For Castings like cylinder heads, a high silicon rod-like 4047 is often chosen because of its lower melting temperature and fluidity along with less of a tendency to get porosity or cracks.
