Found manganese bronze at 2.4mm and 45%silver rods at bunnings and yes you're right the silver is double the price. Will the width of 2.4mm be ok ?
To cut cost, i think i'll be going for manganese bronze but then it says it require a copper and bronze type of flux. This is the only avail flux in Bunnings
https://www.bunnings.com.au/silver-brazing-flux-250g_p5910515. The label say 'Silver Brazing Flux' buti says on the description Ideal for brazing of steel, nickel, brass, copper and stainless steel. Do you think it is ok ?.
