Tungsten Heavy Alloy Crankshaft Balancing |
Tungsten Heavy Alloy (WHA)Crankshaft balancing is crucial to engine performance. In race cars, aircraft or other high-performance engines, professionals who are serious about crankshaft balancing rely on Chinatungsten to provide the high-quality tungsten weights they need.
To determine which tungsten heavy alloy crankshaft weights will work best in your engine, it's important to remember:
Regarding density:
Density of HD17 tungsten = 17 grams/cc
Density of steel = 7.83 grams/cc
To determine the weight of high-density tungsten or steel:
Weight (grams) tungsten heavy alloy = Dia²(inches) x 12.87 x Length(inches) x 17
Weight (grams) steel = Dia²(inches) x 12.87 x Length(inches) x 7.83
When switching from steel to tungsten heavy alloy weights, every gram of steel removed is replaced with 2.17 grams of tungsten heavy alloy. You have therefore increased the weight 117%.
Example:
If you drill out 90 grams of steel and replace it with tungsten heavy alloy, you've replaced 90 grams with 195.3 grams. The net additional weight will be 105.3 grams.
195.3 - 90 = 105.3 grams
An easy way to calculate the net additional weight added when using tungsten heavy alloy is to multiply the grams of steel removed by 1.17.
90 x 1.17 = 105.3 grams added weight
The cost of tungsten heavy alloy weights will be higher because of additional material normally added to length. |
