Spearfishing Kit Adjustable Carbon Fiber Pole Spear 6FT Hand Spear 8FT Travel Pole Spear Diving Fishing Harpoon With Slip Tip

Attention： We have 2 options , 2length: 180cm,,255cm,please choose the right length to order . We not acceptable choose wrong option to change or return .

The slip Tip is made of 17-4PH stainless steel, which has magnetism due to heat treatment. This is normal. 17-4PH stainless steel has high hardness, corrosion resistance, and will not rust in seawater.Relevant information can be mentioned in Google or other relevant professional papers.It canbe testin seawater to see if there is any rusting issue.If you mind ,please don't order .

Carbon fiber composite materials have higher fatigue strength, with the fatigue strength of steel and aluminum being 30-50% of the tensile strength, while carbon fiber composite materials can reach 70-80%

The significant characteristics of carbon fiber are light weight, good fiber size, and high tensile strength, as well as the combination of temperature resistance, wear resistance, and low expansion coefficient.

1. Carbon fiber materials have high strength. The tensile strength of carbon fiber materials is above 3500MPa.

2. The modulus of carbon fiber materials is high. The elastic modulus of carbon fiber materials can reach over 230GPa.

3. Carbon fiber materials have low density and high specific strength. The weight of carbon fiber is 1/4 that of steel and 1/2 that of aluminum alloy. Carbon fiber materials have a strength 16 times greater than steel and 12 times greater than aluminum alloy.

4. Carbon fiber materials can withstand ultra-high temperatures. Under non oxidizing atmosphere conditions, carbon fibers can be used at 2000 degrees Celsius and will not melt or soften at a high temperature of 3000 degrees Celsius.

5. Carbon fiber materials have good low-temperature resistance. It can still be used at temperatures over 100 degrees below zero.

6. Carbon fiber materials have good acid resistance. Carbon fiber materials can withstand corrosion from media such as concentrated hydrochloric acid, phosphoric acid, sulfuric acid, benzene, acetone, etc.

7. Carbon fiber material has small coefficient of thermal expansion and large thermal conductivity. So carbon fiber materials can withstand rapid cooling and heating.
