Ingots are approx. 20kg. Smaller quantities are sold by breaking the large ingots into chunks. To alloy this properly, a temperature of 630 degrees C is needed. For this reason home hobbyists and shooters find it easier to use antimony already alloyed with either tin or lead.
Bismuth is available in slabs of approximately 15kg. This is a necessary component of the low-melting or fusible alloys.
Small quantities are available as chunks broken from the slab.
Bismuth has become popular for making bismuth crystals as seen on videos on internet. It can be remelted and cast again, so often just 500 grams or 1 kg is enough for this purpose, priced at $65 p/kg incl GST.
Bismuth has the unusual property of expanding as it cools.
This is available for electroplating in balls of approx. 600 grams each.
Ingots: Available in 25kg or 5kg ingots (approx)
Sticks: Made to order, approx. 1kg each.
Sheet lead: Available in widths from 150mm to 1400mm and thicknesses from 0.5 mm to 2.65 mm.
Lead Shot: New lead shot in a range of sizes in 10 kg bags - STOCK NOW AVAILABLE - 10KG $93.50
Recovered Lead Shot: Shot recovered from shooting range is cheaper and suitable for weights.
Lead Wire: 4.7mm, 5.5mm, 6.2mm, 9mm. Others sizes made to order - also other alloys such as tin/lead 1:20.
For cutting wire, a heavy duty cutter is available.
Lead Slabs: Cast to order in a range of sizes. Uses are in radiation shielding, weights, or for use in leatherworking.

*Contrary to common usage of the word, ‘tin’ is NOT used for tin cans, roofs or sheds! The mis-use of the word stems from 'tinned cans' and other applications of tin, where tin's properties of protecting food from contamination and iron from rusting have been valuable. 'Tin' roofs and sheds are zinc-coated steel - i.e. galvanised iron or zincalume!
Tin is a beautiful lustrous white metal, 'silvery' in appearance. It oxidises to a soft dull grey (not black like sterling silver!), If it becomes dull it can be polished again to a bright 'silvery' colour. It is the most expensive of the 'base' metals, approximately three times the value of copper and ten times the value of lead.
Tin is low-melting and malleable. This property allows it to be beaten to give an attractive patina, but to make it hard enough for most practical uses it needs to be hardened by small additions of other metals. In the past, lead was sometimes used for this purpose, but the modern standards we apply strictly exclude lead in our pewter.
