954 bronze
Chirpy — Today at 7:27 AM nah, normal 954 bronze doesnt have silicon in it, just al-copper, and some iron, but most people just omit the iron when alloying it themselves [7:29 AM] you need fillets in corners of patterns, and thats why alot of people get hot tears in corners, they tend to add really tiny ones that doesnt really even show up, or none at all, which will create hot tears in castings no matter what you do for gating and will happen in all metals cast tbh, even cast aluminum [7:30 AM] as for shrinkage, it does shrink quite a bit, but if you gate it correctly, it is a dream to cast with and the riser/feeder will shrink like crazy and feed the casting, but that's all that you will have for shrinkage
