Typography
Axia does all the work — one family, four weights, one voice. A condensed humanist grotesque with industrial proportions and open terminals. Engineered, not decorative.
Engineered confidence
Axia is the type equivalent of the Industrial Diplomat. Its tall x-height and narrow proportions carry authority; its open terminals and humanist details keep it warm. It reads industrial without trying to — exactly what we want.
Narrow & efficient
Condensed proportions mean more per line. Headlines feel dense and purposeful, not shouted.
Humanist warmth
Open apertures and subtle stroke modulation give it a human quality — the counterbalance to our deep blues.
Works at both ends
Holds up at 240px on a brand hero and at 9px on a datasheet spec table. One family, full range.
Four weights, four jobs
Four weights cover the whole system. Never introduce a fifth without approval from brand.

The full scale
Every role named, sized, and paired. Use the token name in code so the scale can adjust centrally. Line-heights are tight on display, generous on body.
| Token | Specs | Sample |
|---|---|---|
| $display-01 | 88 / 90 · Black · −2.5% | The European standard. |
| $display-02 | 64 / 67 · Black · −2.0% | Proven at pilot scale. |
| $h1 | 56 / 59 · Black · −1.8% | Supply chain sovereignty. |
| $h2 | 32 / 38 · Black · −1.8% | Commercial readiness, on the roadmap. |
| $h3 | 14 / 18 · Medium · +8% · caps | H3 · Quisque turpis iaculis non pretium |
| $h4 | 20 / 26 · Bold · −0.2% | Subsection / card heading |
| $body-lg | 19 / 29 · Regular | Lede and intro paragraphs. Used once per section to set the register. |
| $body | 16 / 26 · Regular | Standard paragraph text. Carries the working voice across web and print. |
| $body-sm | 14 / 22 · Light | Small body — captions, footnotes, fine print, supporting paragraphs. |
| $eyebrow | 11 / 13 · Medium · +14% · caps | Eyebrow · Messaging pillar |
| $caption | 12 / 17 · Medium · +2% | Caption · figure notes, status meta, UI helpers |
| $mono | 12 / 18 · Axia Regular | data · tokens · codes · Wh/kg · −40°C → +65°C |
How the scale composes
Three canonical compositions. Web hero, editorial body, and spec sheet — each uses the same scale, just different weights and grounds.

The holy trinity.
Performance, safety
and sustainability.
Altris's sodium-ion batteries have outstanding performance in terms of longer life, more flexible working temperatures, and safety.
They have an energy density on par with the most widely used lithium-ion chemistry, LFP, plus very similar development and production equipment and processes. The economic logic follows the physics: abundant, European raw materials become a resilient supply chain.

The display treatment
Use Axia Black with tight tracking and stacked lines for hero headings, covers and key statements.
by salt.
Compressed Black
Set the headline in Black with tight tracking and deliberate line breaks. Keep each line short enough to read as a single thought.
Usage rules
Small set, big impact. These are the rules that keep the voice consistent across a deck, a datasheet, and a billboard.
Black for display only
Axia Black is for H1, display numbers, and hero moments. Never set body copy in Black — it over-claims and reduces readability.
H3 is always uppercase
Use H3 as an all-caps Medium label with +8–10% tracking. Never title-case H3. Keep it short (≤ 6 words).
Tracking tightens as size grows
Axia is compact. Pull tracking in progressively at display sizes: −1.8% at H1, −2.5% at display-01.
Measure caps at 70ch
Body copy runs between 55–75 characters per line. Longer and it tires; shorter and it fragments the voice.
One accent word max
High Voltage highlights in headlines are powerful — but only as the punchline. One word per headline, never two.
Axia for every voice
Use Axia Regular for data labels, units and annotations. Use Bold for emphasis and Black for headline figures.
