Overview
This casting alloy is intended for reloaders who want to harden recovered lead while keeping the melting process straightforward. It is made from 70% lead and 30% antimony, and Brownells notes that it melts at around 745°F. Because it is sold by the ingot with approximate weight, it fits well into bench setups where consistent alloying matters more than convenience packaging. The use of virgin metals, rather than scrap, is a practical detail for those who want a clean starting material for bullet casting.

Considerations & Trade-offs
- Sold by the ingot with approximate 5 lb weight, so exact quantity can vary slightly from piece to piece.
- This alloy is intended for hardening recovered lead; it is not a general-purpose casting material for every application.
- It melts at around 745°F, so it requires enough heat capacity and temperature control for consistent use.
- Brinell hardness is described as difficult to determine here, so selection is based on antimony content rather than a specific hardness rating.

Frequently Asked Questions
What is Brownells Superhard Bullet Casting Alloy made of?
It is listed as 70% lead and 30% antimony.
How is this alloy sold, and what does one ingot weigh?
It is sold by the ingot, and each ingot weighs roughly 5 pounds. The listed weight is approximate.
What is this alloy intended for?
The description says it is a source for hardening recovered lead.
Does the product list a Brinell hardness value?
No. The description says Brinell hardness is difficult to determine on this alloy, so it is sold based on the percent of antimony instead.
Is this alloy made from scrap or virgin metal?
It is described as being made from virgin metals, not from scrap, so the alloy is intended to provide clean material.
