Revision as of 21:12, 29 January 2017
- 40 cents - 1/2" - [1]
- 10 cents - 10x2 N50 - [2]
- 30c 1/2" [3]
- 40 cents 12x3 n52 - [4]
- 20 cents @ 100, 12x3 n52 - [5]
- 17 cents 12x3 from china - [6]
- 17 cents 12x3 @ 1000 from UK - [7]. This appears to be the best option.
- 7 cents 10x2 HK (looks like 1/16" thickness) - [8]. While this looks cheaper, this is not because of the lower strength of 10x2.
- 11 cents 12x2 - [9]
- 18 cents 20x10x2 - [10]
Strength
- 12x3mm appears to be 8 lb - [11]
- 10x3mm is 5.5 lb - [12]
- 20x10x2mm is 4.8 lb - [13]
- 10x2mm n52 is 2.6 lb - [14]
- 12x2mm n52 is 3.8 lb - [15]
Notes
- 2 mm compared to 3 mm appears to be 1/2 as strong. 2 mm is really 1.6 mm, of 1/16", compared to 1/8", or 3 mm. That makes sense.
- Thus, it's more favorable to go with 3mm thickness.
Tested
- Ebay [16] - 25 for $11 - 48 cents.
