It would seem like metal pen ideas for electronic pens are finding far more well-liked. In this evaluation, I will share with you my conclusions on how metal pen guidelines carry out for creating and drawing, and no matter whether they can scratch the glass show.
Can metallic scratch glass
For steel to scratch glass, the steel has to be more difficult than glass, and there has to be a position or chopping edge.
Below a listing of metals and their Mohs scale of mineral resistance (hardness):
- Direct: 1.5
- Tin: 1.5
- Zinc: 2.5
- Gold: 2.5-3
- Silver: 2.5-3
- Aluminum: 2.5-3
- Copper: 3
- Brass: 3
- Bronze: 3
- Nickel: 4
- Platinum: 4-4.5
- Steel: 4-4.5
- Iron: 4.5
- Palladium: 4.75
- Rhodium: 6
- Titanium: 6
- Hardened metal: 7-8
- Tungsten: 7.5
- Tungsten carbide: 8.5-9
Glass has Moh hardness of 5.5 to 7 dependent on how the glass is designed.
You can see from the listing above that most metals are softer than glass apart from for hardened metal and specified metallic alloys. Sand can scratch glass though simply because both sand and glass are Silicon Dioxide.
Primarily based on my screening, the steel pen strategies did not scratch glass.
The initial metallic pen suggestion I noticed is from the Huawei M Pencil 2 in 2021. That pen idea is coated with platinum (4 – 4.5 hardness). Following that, metal pen tips became a lot more prevalent.
These are the pen nibs I acquired for tests from prime remaining to bottom proper:
- HB plastic nib (related to primary Apple Pencil tip)
- 2B plastic nib
- Needle point with translucent plastic system
- Needle level with white plastic overall body
- Round place with white plastic overall body
The metallic utilized is copper (3 hardness) with nickel plating (4 hardness) and that’s why are in concept softer than glass.
This is the needle place idea. The slim needle stage lets you to see the line beneath it more easily.
What I do not like about metal strategies is the audio they make when they occur in make contact with with glass. Metallic stage is marginally smoother than the original Apple Pencil tip.
Draw back of this metal needle tip is there is wobble or jitter when drawing gradual diagonal traces.
Tension sensitivity operates wonderful but listed here you can see apparent wobble with the diagonal strains.
One more downside is tilt activates very easily by tilting the pen a little rather of significantly reduce.
I pressed down difficult on my iPad Pro to scratch the glass exhibit but I could not build any scratches.
The round steel tip performs greater than the needle suggestion.
It is really feasible to draw straight diagonal strains little by little with the round steel suggestion.
Stress sensitivity will work effectively.
Tilt sensitivity will work very well with the round metallic tip much too.
This is the 2B plastic suggestion is definitely nice. There is significantly extra resistance than the initial Apple Pencil suggestion. You can locate these on the internet for a lot less than US $1.50 each. That is a huge variation from the silicone PenTips2 I reviewed lately which is US $15 each. PenTips2 has a little additional resistance the 2B plastic nib demonstrated over is far more really worth the income due to the fact it can be way extra inexpensive.
2B plastic suggestion can draw gradual diagonal strains straight without wobble.
Stress sensitivity works wonderful.
Tilt sensitivity performs great.
Are steel pen recommendations secure on glass shows? Certainly.
Do I advise metal pen strategies? It is dependent. If you locate that you dress in down your plastic recommendations that normally, possibly it’s better to get steel strategies considering that steel is much more resistant to dress in and tear.
I never like how the metallic ideas seem on glass. I favor the 2B plastic nib which has resistance on glass and that can give you more regulate when drawing. For creating, you must just go with HB suggestion or the first Apple Pencil tips which are smoother on glass. Smoother pen ideas are improved for producing quick.
You can locate these steel pen suggestions on AliExpress and they are all pretty very affordable.
