g4321 Posted December 26, 2005 Report Share Posted December 26, 2005 What does anyone suggest I use to make a heat shield for the front pipe of my TLR, I have already made one but am interested to see what the opinions of others are. Alloy Steel / Stainless Steel Titanium Quote Link to comment Share on other sites More sharing options...
feetupfun Posted December 26, 2005 Report Share Posted December 26, 2005 Assuming you are making a heat shield to reduce the heat transfer from the pipe to the carburettor, you should use stainless steel as it is the worst conductor of heat of the materials you mentioned. Titanium and aluminium alloys are very good conductors of heat so when bare they make poor heat shields. If it was possible to fit insulation to the heat shield, these materials would also be OK. Steel has higher conductivity than stainless steel yet is no lighter so is not as good as stainless steel as a heat shield. Quote Link to comment Share on other sites More sharing options...
brian r Posted January 3, 2006 Report Share Posted January 3, 2006 I'm not one to ague but titanuim is a very bad heat conductor. Aluminum is 87.7 BTU/FT*H*F 304 SS is 8.6 BTU/FT*H*F Titanium is 3.8 BTU/FT*H*F We use titanium spacers to isolate heat from manifolds for injection molding hot runners. Copper is about as high as you can get (174BTU/FT*H*F), Titanium is about as low as you can get. Personally I'd look at a phenolic. Stinks when you macine it!
