Had the oil filter cap on my car break today, made out of die cast aluminum, got me to thinking about reel frames. Now we all know that the best reels have aluminum frames, but not all aluminum is the same. For those starting out we routinely get questions about what to buy, naturally the advice goes make sure it has an aluminum frame, quality bearings (its not the bearing count but the quality that counts), brass gearing, etc. I'm starting to question a portion of that formula, we should; I believe encourage, newbies to buy either a machined or extruded aluminum frame. I know it is something that I make sure of, if the reel has a die cast aluminum frame I pass. Die cast aluminum is not as strong as machined or extruded aluminum, in fact it could be weaker than graphite. Many of us may remember metal that was called "pot metal", it was weak and soft, pot metal is die casted. The die cast process can not guarantee uniform density of the metal throughout the frame, and nearly all has weak spots where the metal didn't cool correctly or has impurities, graphite on the other hand is at least uniform in density and strength. If I had to pick between the two graphite or die cast I think I would go with the graphite if it is from a reputable manufacturer. For example most manufacturers bottom line reels are graphite framed, the next step is die cast, the die cast frame reels cost more, but because of the manufacturing process they may not be as strong as the graphite, the next step is either machined or extruded aluminum. If your budget allows always pick an aluminum frame that is either machined or extruded, doing less and you are short changing yourself in quality and durability.
